Changelog
=========

January 11, 2023 - bake-toolkit 2.72.0
    * Change all deprecated functions ``File.exists`` to ``File.exist`` for compatibility to Ruby 3.2.

December 13, 2021 - bake-toolkit 2.71.0
    * Add ``--abs-paths-in`` for compiler command lines and ``--abs-paths-out`` for compiler output. This splits the still existing ``--abs-paths``.

December 8, 2021 - bake-toolkit 2.70.1
    * Fix handling of file specific flags and defines in combination with the command line argument ``--abs-paths``.

April 15, 2021 - bake-toolkit 2.70.0
    * Add ``args_end`` attribute to Collection.meta, which appends parameters at the end of the bake calls after the additional arguments from command line.
    * Print a warning if an ``Adapt`` with toolchain condition shall be applied to configs which don't have a toolchain defined (yet).

March 26, 2021 - bake-toolkit 2.69.0
    * Add wildcard support for ``Copy``, ``Move`` and ``Remove`` commands in Project.meta.
    * Add support for absolute paths in Collection.meta.
    * Normalize paths in in Collection.meta (e.g. resolving ``..``). This also prevents that the same config is built multiple times
      if the path points to the same project from different workspace roots.

March 8, 2021 - bake-toolkit 2.68.1
    * Add support/workaround for latest ARM GCC which writes ``<drive letter>\:\some\folder`` into dependency files on Windows systems (note the additional ``\`` sign).

March 2, 2021 - bake-toolkit 2.68.0
    * Enhance ``--abs-paths`` so it affects not only error messages but also sources, objects, includes, library and executable names.
    * Add project filter to adapt-command-line-option, e.g. ``--adapt coverage[lib1,lib2,safety*]``
    * Add array syntax for *CommandLine* in Project.meta to wrap very long lines.
    * Switch theme of documentation from Bootstrap to ReadTheDocs.

January 7, 2021 - bake-toolkit 2.67.0
    * Add variable *$(OriginalDir)*, which points to the directory of the containing meta file. Useful for relative paths from Adapt files.
    * Add *outputDirPostfix* to (Default)Toolchain. It can be used for special builds like MISRA checkers.
    * Add *ExcludeDir* to bakery. Up to now it was only possible to exclude by project name (with wildcards), but not complete folder trees.
    * Add robustness measure: now every dependency from bake to other gems is specified with hardcoded version on installation time and runtime.

October 23, 2020 - bake-toolkit 2.66
    * Bugfix: --list failed when Project.meta contains an Adapt
    * Bugfix: circular extension of projects not detected during load
    * Changed: llvm-lib is now used to archive when using Clang on Windows
    * Added: Automatic path completion for Makefile command, e.g.

      .. code-block:: console

          Makefile "someProject/Makefile", target: all, lib: "someProject/output/libresult.a"

September 18, 2020 - bake-toolkit 2.65.2
    * Bugfix: if pathname length of dependency file is > 255 on Windows, the compilation check might break.
    * Added: now Adapts can be also filtered
    * Cosmetic: replaced mouse-over-javascripts in syntax pages of the documentation by static texts.

September 7, 2020 - bake-toolkit 2.65.1
    * Bugfix: __THIS__ in Project.meta was resolved to main project name, not local project name
    * Bugfix: Fixed an exception with old Ruby versions where "fiddle" is not available

August 26, 2020 - bake-toolkit 2.65.0
    * Bugfix: Dependency to gem thwait 0.1.0 instead of latest version (they messed it up, latest gem might abort the builds on some systems)
    * Bugfix: Skip CompilationCheck on dry run
    * Added: CLANG_BITCODE toolchain

July 28, 2020 - bake-toolkit 2.64.4
    * Bugfix: Fixed the check in 2.64.3.

July 28, 2020 - bake-toolkit 2.64.3
    * Bugfix: Algorithm for CompilationCheck had quadratic instead of linear complexity.

July 24, 2020 - bake-toolkit 2.64.2
    * Added: experimental dev-feature "retry-linking" (not for public use)

July 24, 2020 - bake-toolkit 2.64.1
    * Bugfix: CompilationCheck did not work correctly in special configurations, e.g. LibraryConfig without files

July 22, 2020 - bake-toolkit 2.64.0
    * Added: CompilationCheck to check for included/excluded files in a build
    * Cosmetic: Internally using fiddle instead of Win32Api (getting rid of deprecated warning when starting bake)

June 22, 2020 - bake-toolkit 2.63.2
    * Changed: bake does not abort anymore if cache files cannot be written.

June 17, 2020 - bake-toolkit 2.63.1
    * Changed: "-Z dep-overview=<json>" exits now after writing the information into the json file.
    * Added: Warning in bakery if referenced projects or configs cannot be found.

June 10, 2020 - bake-toolkit 2.63.0
    * Bugfix: bake did not wait for a non-indepenent step (e.g. a generator) if it can be reached via multiple ways in the dependency hierarchy.
    * Added: Internal developer feature "-Z dep-overview=<json>" for intelligent CIs.
    * Added: Forbid include dirs with a leading space, e.g. *IncludeDir " include"*.
    * Added: An info is printed out if path magic is used in IncludeDir.
    * Added: Files have an optional attribute "linkDirectly", which means they are not archived in a lib, but linked directly to the executable.

May 14, 2020 - bake-toolkit 2.62.0
     * Added: bake now understands dependency files from Axivion, which makes incremental build possible.

May 4, 2020 - bake-toolkit 2.61.0
     * Added: possibility to specify additional root files with -w (they doesn't need to be called roots.bake).
       There are different use cases for this, e.g. having a Collection.meta outside the workspace.
     * Added: Variable *$(WorkingDir)* which points to the directory from which bake was called.
     * Added: *CompilationDB <file>* as option for main configs to generate compilation database. "--compilation-db" from command line will overrule this.

       .. code-block:: console

           ExecutableConfig Release {
             CompilationDB "$(ProjectDir)/compile_commands.json"
           }
     * Bugfix: build config could not be set after -j without number, e.g. "bake -j UnitTestBase"
     * Added: additional folder name case check on Windows (similar to the one from 2.60.2 but it covers other use cases)
     * Added: *Adapt scope* feature now also takes scopes from main config into account, not only from the to-be-adapted config.

March 25, 2020 - bake-toolkit 2.60.2
     * Added: a warning is printed if two folders differ only in letter case either on file system or due to (Windows) shell issues. Example:

March 20, 2020 - bake-toolkit 2.60.1 (not officially released)
     * Changed: dependencies are now injected to other injected dependencies. This should solve some bugs, hopefully it does not introduce other problems.

March 17, 2020 - bake-toolkit 2.60.0
     * Bugfix: the build order of configs were wrong when injecting dependencies.
       If e.g. a dependency to a generator was injected to a library, it could happen that the library was built before the generator was executed.

March 6, 2020 - bake-toolkit 2.59.0
     * Partly reverted changes introduced in 2.57.0. New behaviour:
       "Files" specific Flags/Defines are still first-is-best, but if Flags/Defines are specified for a single file it overrules previous definitions.

March 4, 2020 - bake-toolkit 2.58.0
     * Added: -j without number means that bake is using as many threads as cores are available.
     * Cosmetic: Added a warning if in Project.meta Flags/Defines are specified for a single file but ignored due to a previous definition.

       .. code-block:: console

           Files "src/*.cpp" # has higher priority (in this case *.cpp shall be have no additional flags/defines)
           Files "src/main.cpp" {
             Flags "-abc"    # ignored, overruled by file pattern above --> warning
           }

February 20, 2020 - bake-toolkit 2.57.0
     * Bugfix: if a file is explicitly defined in Project.meta, the flags/defines must not be overwritten even if flags/defines were defined later via a file pattern.

       .. code-block:: console

           Files "src/main.cpp" # must not be complied with "-abc"
           Files "src/*.cpp" {
             Flags "-abc"
           }

     * Added: support for Ruby 2.7.x.

January 20, 2020 - bake-toolkit 2.56.0
     * Added: new cmd argument --lines <start_line>:<end_line> for bake-format tool which tells to format lines only in range between start and end lines.
     * Added: new bake-rtext-service cmd tool, which runs the RText language protocol server and can be used by the IDE to provide the syntax highlighting, auto completion, errors annotation and model navigation.
     * Bugfix: Removed debug output for compilation-db, accidentally added with 2.53.
     * Bugfix: fixed an exception using scopes for adapts.

November 27, 2019 - bake-toolkit 2.55.1

November 21, 2019 - bake-toolkit 2.55.0
     * Added: default number of compiling threads is now equal to the number of logical processors instead of hardcoded 8 (only for Ruby >= 2.2).

     * Changed: ArtifactExtension can be used to extend ArtifactName.

October 14, 2019 - bake-toolkit 2.54.1
    * Reverted: The change from 2.54: "(Windows only) If a case mismatch is detected between Files definition in Project.meta and filesystem, the compilation will be aborted."

    * Bugfix: bakery regex did not take comments into account when parsing Project.meta.
    * Added: "strict" attribute to match only the specified Adapt config type.

    * Added: all conditions like "toolchain" support list format, e.g. "GCC;CLANG".
    * Added: "compileOnly" annotation for "Files" which means that they shall be compiled, but not archived or linked (experimental feature, might be changed in future).
    * Added: improved GCC compiler error parser.
    * Cosmetic: when enforcing local paths e.g. for outputDir, "./" will be removed for nicer output.

March 25, 2019 - bake-toolkit 2.51.2
    * Added: --dotc creates the dot graph AND compiles the projects as usual (in comparison to --dot).

March 21, 2019 - bake-toolkit 2.51.1
    * Bugfix: under certain cases the same Adapt.meta could be found twice which results into a warning.
    * Changed: if a cmd of a Set (variable) returns with !=0, the output of cmd is now printed out to get an idea why it has failed.

March 13, 2019 - bake-toolkit 2.51.0
    * Changed: refactored calculating include folders. Now it's much faster than before! However, the order of include folders may have changed for ambiguous configurations.
    * Changed: merge-include feature refactored after getting some feedback.

February 7, 2019 - bake-toolkit 2.50.0
    * Added: command line option "--merge-inc" which copies all include files into one temprary folder and invokes the compiler with just one include path.
    * Added: command line option "--file-cmd" which writes all command line arguments into a file and hands it over to the compiler (with "@" in gcc and dcc).
    * Added: "adapt" supports now lists of projects/configs (additionally to wildcards), separated with ";".
    * Added: added Cuda support for GCC toolchain (experimental)

January 23, 2019 - bake-toolkit 2.49.0
    * Added: Support for IAR compiler.

November 28, 2018 - bake-toolkit 2.48.3
    * Bugfix: Removed accidentally added debug output which was introduced in 2.48.2.

November 8, 2018 - bake-toolkit 2.48.2
    * Bugfix: Now compatible with new QAC folder structure (problem was that user-suppressed warnings in qac.cct were not suppressed).

September 20, 2018 - bake-toolkit 2.48.1
    * Bugfix: Compiler prefix change reverted for C and CPP, only assembler still has the new ASMCompilerPrefix.

September 7, 2018 - bake-toolkit 2.48.0

    * Bugfix: in same cases the OutputDir variables were not substituted correctly in 2.47.0.

July 27, 2018 - bake-toolkit 2.47.0
    * Added: *Sleep*, *MakeDir*, *Remove*, *Copy* and *Move* commands in Project.meta.
    * Added: option -D to add defines via command line.
    * Added: DCC case check with --diab-case-check for Windows. Makes sense to start the compilation again after full build was successful with this parameter.
      With this parameter the code is not compiled, only checked. It takes around the time of a compilation. Note, with GCC the check is done during compilation in
      "no time" - enhancement request ticked filed at Windriver to make that possible with Diab.
    * Improved: Cyclic variable substitution
    * Removed: support of Visual Studio (not Visual Studio Code)
    * Removed: official support of Ruby 1.9

    * Added: Makefile command has new attribute **noClean**. If set to true, the target *clean* will not be executed when project is cleaned. Default: false.
    * Added: Makefile command has new attribute **changeWorkingDir**. If set to false, bake stays in project's directory instead of changing into makefile's directory. Default: true.
    * Added: Before executing the makefile, bake sets the environment variables $(BAKE_XX_COMMAND) and $(BAKE_XX_FLAGS), whereas XX is one of CPP, C, ASM, AR or LD.

May 4, 2018 - bake-toolkit 2.45.0
    * Changed: it is possible now to specify adapt files directly with *--adapt <filename>*
    * Changed: variables can be set by calling a script (see *Set <var>, cmd: <script>*). If the script fails, bake aborts now with an error instead continuing with a warning.
    * Added: allow additional bake arguments specified per project in a bakery collection
    * Bugfix: bakery collections can now reference a quoted project name and names with "-" or ":"
    * Bugfix: under rare circumstances bake did not abort with an error if the main directory specified with -m does not exist

    * Bugfix: in Adapt.meta "__MAIN__" in project now applies to *all* configs in the main project
    * Changed: "--compilation-db" now generates absolute paths if "--abs-paths" is set

February 26, 2018 - bake-toolkit 2.44.0
    * Added: Case sensitivity check of C/C++ include files (on by default!), use --no-case-check to disable it
    * Added: Variable $(Uid), a CRC32 over relative path to main project dir plus main config name.

    * Bugfix: fixed prebuild feature after changes in 2.43.0

February 12, 2018 - bake-toolkit 2.43.1
    * Bugfix: exception when using file specific flags and defines fixed (bug introduced with 2.43.0)

February 12, 2018 - bake-toolkit 2.43.0
    * Bugfix: when building with "stop on first error" (-r) and an error occurs in PreSteps or PostSteps of a dependency, the error status was not correctly handled.
    * Added: option to keep file endings for object files, which means file.cpp becomes file.cpp.o instead of file.o:

      .. code-block:: console

          DefaultToolchain keepObjFileEndings: true

    * Added: the hard coded list for source file endings for a specific compiler (CPP, C, ASM) can now be overwritten, e.g.:

      .. code-block:: console

          Compiler CPP {
              SrcFileEndings ".cpp, .c, .cxx"
          }

    * Bugfix: Invalid command line arguments could have been recognized as valid, e.g. "--rebuild123" was interpreted as "--rebuild", there was no complaint about the "123" - affected versions: >= 2.34.4.

March 27, 2017 - bake-toolkit 2.35.0
    * Bugfix: Rubys IO.select() is not thread-safe by itself. It could happen, that bake hangs and the user has to press a key (due to waiting for already closed stdin stream) - affected versions: >= 2.33.0.
    * Bugfix: if no roots.bake was found, the default root ("<mainProject>/..") was added to the root list even when -w options were added on command line - affected versions: >= 2.26.0.
    * Added: roots defined on command line (with -w) and entries in roots.bake can be equipped with an optional search depth setting, e.g. "-w some/folder,3".
      This can reduce startup time of bake avoid multiple-projects-found-warnings.

March 16, 2017 - bake-toolkit 2.34.4
    * Added: CommandLine and Makefile have a new argument. If *independent: true*, they are not executed exclusively but in parallel to other projects/configs.
    * Added: -j can now be used without space and -v with space, e.g. -j8 or -j 8, -v2 or -v 2.
    * Internal: under the hood optimizations for parallel build.

March 9, 2017 - bake-toolkit 2.34.3
    * Changed: slightly changed thread handling (internal change).

March 9, 2017 - bake-toolkit 2.34.2

    * Changed: improved debug-thread output.
    * Bugfix: killing processes on failure may not work correctly.

March 9, 2017 - bake-toolkit 2.34.1
    * Added: --debug-threads to debug multithread problems.
    * Bugfix: Cleaned up thread data structure. I don't think this is a real problem, but this depends on OS implementation of Ruby's thread lib".
    * Bugfix: On Linux console bakery abort output corrected.

March 8, 2017 - bake-toolkit 2.34.0
    * Added: With parameter -O the output can be synchronized now for parallel build.

    * Bugfix: Fixed ctrl-c for bakery in some shells.

March 2, 2017 - bake-toolkit 2.33.0
    * Changed: Projects are built in parallel now (not only the files within a single project). This implies a change in the output.

February 27, 2017 - bake-toolkit 2.32.0
    * Changed: Per default configs without *Files* and *Steps* are not counted and printed out anymore (because nothing has to be done), use *-v2* to show them again.
    * Changed: Templates used for *--create* are now closer to ESRLabs standard. Exit code corrected (was 1 instead of 0), thanks to flxo for the pull request.
    * Changed: Promoted warning "files are compiled more than once" to error.

February 23, 2017 - bake-toolkit 2.31.5

February 3, 2017 - bake-toolkit 2.31.0
    * Added: Dry run via command line parameter --dry.
    * Added: Support for compiler, archiver and linker prefixes, can be used for e.g. sccache.
    * Added: "If" is now an alias for "Adapt". To negate the conditions, use "Unless".
    * Added: For Adapts in Project.meta the "project" attribute is now "__THIS__" per default, which should be correct in almost every case.
    * Cosmetic: Getting rid of warning output if paths start with ".", e.g. IncludeDir "./local/abc".
    * Cosmetic: Only print the first out-of-date meta file when checking cache.

January 20, 2017 - bake-toolkit 2.30.0
    * Added: New adapt option "push_front".
    * Added: Project.meta and Collection.meta will be searched upwards if not found in current directory (or the directory specified with -m).
    * Changed: --doc opens online docu per default. You can install the offline docu with --install-doc.
    * Added: --debug prints more information when reading the cache, use this as feedback if you think caching does not work correctly.

January 12, 2017 - bake-toolkit 2.29.4
    * Added: qac: Workaround if QAC cannot handle the amount of errors and returns with != 0. The build must not be aborted, instead the printed errors should be parsed.

January 12, 2017 - bake-toolkit 2.29.3
    * Bugfix: qac: QAC bails out if modules have too many errors, added workaround and additional hint in output.

January 11, 2017 - bake-toolkit 2.29.3
    * Bugfix: Some commandline checks in combination with --file-list were outdated.

January 10, 2017 - bake-toolkit 2.29.2
    * Changed: --file-list output now written into files instead of stdout, see "bake -h".
    * Bugfix: adapt condition "toolchain" not evaluated correctly in all cases

January 4, 2017 - bake-toolkit 2.29.0
    * Added: CleanSteps, executed only when calling bake with "-c" or "--rebuild".
    * Added: Wildcard "*" is allowed for project/config names in Adapt.
    * Bugfix: In certain circumstances an Adapt was not applied to subconfigs of the Project.meta where Adapt was defined.

January 4, 2017 - bake-toolkit 2.28.1
    * Bugfix: Build does not break anymore if "LintPolicy" is still defined in Project.meta. Now only a warning is printed out.

January 3, 2017 - bake-toolkit 2.28.0
    * Added: private flag for configs (cannot be referenced directly from outside of the project).
    * Added: attribute "echo: off" for CommandLine and Makefile.
    * Added: "--file-list" shows all files and headers of the projects.
    * Removed: lint support.

    * Changed: qac: again slightly modified cip workaround.

January 2, 2017 - bake-toolkit 2.27.0
    * Added: local *Adapt* with conditions (e.g. toolchain), see :ref:`adapt_reference`.
    * Changed: qac: cip workaround slightly adapted, removed temporary debug output.

December 23, 2016 - bake-toolkit 2.26.1
    * Changed: qac: next try to add a workaround for the cip file bug.
    * Cosmetic: fixed possible wrong message when reloading metas ("corrupt" instead of "changed")

December 20, 2016 - bake-toolkit 2.26.0
    * Changed: before this version, "-w" command line args (which define the workspace roots) have overwritten roots.bake file. Now these roots will be
      merged. First "-w", then roots.bake. Note: this will not break current builds.

December 16, 2016 - bake-toolkit 2.25.1
    * Bugfix: a null pointer exception could occur in 2.25.0, which happened in a complex scenario with multiple dependencies to a default config which extends another config with dependencies.
      Luckily, this bugfix goes along with a small performance improvement when loading uncached meta files.

December 15, 2016 - bake-toolkit 2.25.0
    * Changed (!): before this version, all "IncludeDir"s were evaluated prior to the "Dependency"s to calculate the include path string for the compiler. Now the line order
      is taken into account. To get the same include path string as in 2.24.x, shift all "IncludeDir"s in front of the first "Dependency".
    * Added: it is possible to mark an IncludeDir with "system: true", which means that e.g. for gcc "-isystem" is used instead of "-I". Very useful for third party libs.
    * Bugfix: qac: adapted parser to new gcc version strings. On some machines an incorrect CCT was chosen.
    * Bugfix: when building with "-p <projectname>", bake has not only built <projectname>, but also all injected dependencies of <projectname>, which was not intended.
    * Added: qac: additional step to generate reports, activate it manually with "--qacstep report", see documentation.
    * Cosmetic: Adapt.meta files are also cached now.
    * Temporary: cip bug workaround from 2.24.2 does not work, added some debug output to get more infos - sorry for the spam - will be removed soon.

December 5, 2016 - bake-toolkit 2.24.3
    * Added: qac: if "<mainConfigName>Qac" is found in main project, it will be used instead of "<mainConfigName>"
    * Added: First version of bake-format script, thanks to gizmomogwai

November 24, 2016 - bake-toolkit 2.24.2
    * Bugfix: qac: fixed recognition of platform for cygwin with gcc >= 5.0
    * Bugfix: qac: default folder of qacdata is now <main project>/.qacdata instead of <working dir>/.qacdata
    * Bugfix: qac: workaround for "qacli admin": retry up to 10 times if cip file is empty (getting compiler data)

November 16, 2016 - bake-toolkit 2.24.1
    * Bugfix: qac.cct was not appended if --cct is used.
    * Bugfix: qac: abort if QAC_HOME is set to empty string.

    * Bugfix: qac: output was not synced immediately to the console on some systems.
    * Changed: qac: patching of cct introduced with 2.23.9 now opt-in via command line argument: --qaccctpatch.
    * Changed: qac: default build output directory is now "build/.qac/" instead of "build/" (which does not overwrite regular build output anymore).
    * Changed: if default build folder is used, the parent folder "build" will be also removed when the project is cleaned if the "build" folder will become empty.
    * Added: bakeclean script to delete all .bake, .bake/../build and .bake/../build_* folders
    * Added: prebuild feature now uses objects instead of the library if objects exist.
    * Changed: default executable file ending on non-Windows systems now "" (except Diab and Greenhills, here it is always ".elf").

October 26, 2016 - bake-toolkit 2.23.12
    * Bugfix: qac: now also files from .qacdata folder are filtered out.
    * Bugfix: qac: modules were not be filtered out correctly, e.g. swcAbcd was not filtered out if swcAbc was compiled.
    * Removed: qac: qac.rcf will not be searched anymore (most probably this feature was never used).
    * Added: qac: qac.cct will be searched up to root; if found, the content will be appended to the original cct unless specified otherwise.

October 26, 2016 - bake-toolkit 2.23.9
    * Bugfix: qac: command line options not correctly handed over to bake (bakeqac has been aborted in this case).

    * Cosmetic: qac: if license retry timeout is reached, an additional info is printed.
    * Added: qac: With --qacdoc a link to the appropriate documentation page is printed for every warning.

October 17, 2016 - bake-toolkit 2.23.7
    * Changed: renamed qac build steps from create, build and result to admin, analyze and view (the original qac names).
    * Bugfix: qac view step might have been executed although build has been failed.
    * Bugfix: qac view step with never executed analyze step might have been crashed.
    * Bugfix: qac C++11 and C++14 switches were broken.

October 14, 2016 - bake-toolkit 2.23.6
    * Bugfix: qac license refused error now really shown.
    * Changed: QAC_RCF environment variable not supported anymore. Instead a file qac.rcf will be searched upwards from bake main project folder.

October 5, 2016 - bake-toolkit 2.22.0
    * Changed: when building, only the return value of the compiler is taken into account, not the result of the error parser anymore. Old behaviour can be switched on by command line argument.
    * Bugfix: again fixed reading of dependency files, added several unittests.
    * Internal: based on new rtext 0.9.0 and rgen 0.8.2 now.

September 30, 2016 - bake-toolkit 2.21.0
    * Changed: version and time infos are suppressed now per default. Version can be seen with --help or --version, time can be seen with --time.

January 7, 2015 - bake-toolkit 2.0.3
    * Changed: default configuration is chosen if configuration name is omitted. This applies to command line as well as to Dependency definitions, e.g.:
        * Project.meta

            .. code-block:: console

                Dependency canDriver        # no config attribute

        * Command line

            .. code-block:: console

                User@Host:~$ bake -m bla/myProj

        .. note::

            To show the possible configs of a project, use the `--show_configs` command line option.


    * Changed: more than one config of a project can be used in one build.

        Example:

        .. code-block:: console

            Dependency canDriver, config: C1
            Dependency canDriver, config: C2


        To reference a config of the current project, omit the project name, e.g.:

        .. code-block:: console

            Dependency config: C3

        To build a single project, you can still use -p command line argument:

        .. code-block:: console

            User@Host:~$ bake Debug -p canDriver

        However, if canDriver has more than one config in the workspace, all configs will be built. To build only a single config, use a comma separator like this:

        .. code-block:: console

            User@Host:~$ bake Debug -p canDriver,C1

    * Changed: the default output folder has been changed due to the new feature of having several configs of a project in one workspace.

        .. warning::
            Be careful if you have something like this in Project.meta:

                ExternalLibrary "bspCoreZ6/$(MainConfigName)_$(MainProjectName)/src/coreZ6/startup/startupCode.o", search:false

            This refers to the old output directory. Change it or if you want to support old and new bake versions,
            write a PreStep which copies the file from the new location to the old one.
