With - the :generator:`Ninja` generator, this places the steps in the - ``console`` :prop_gbl:`pool <JOB_POOLS>`. Options are: - - ``USES_TERMINAL_DOWNLOAD 1`` - Give download terminal access. - ``USES_TERMINAL_UPDATE 1`` - Give update terminal access. - ``USES_TERMINAL_CONFIGURE 1`` - Give configure terminal access. - ``USES_TERMINAL_BUILD 1`` - Give build terminal access. - ``USES_TERMINAL_TEST 1`` - Give test terminal access. - ``USES_TERMINAL_INSTALL 1`` - Give install terminal access. - - Other options are: - - ``STEP_TARGETS <step-target>...`` - Generate custom targets for these steps - ``INDEPENDENT_STEP_TARGETS <step-target>...`` - Generate custom targets for these steps that do not depend on other - external projects even if a dependency is set - - The ``*_DIR`` options specify directories for the project, with default - directories computed as follows. If the ``PREFIX`` option is given to - ``ExternalProject_Add()`` or the ``EP_PREFIX`` directory property is set, - then an external project is built and installed under the specified prefix:: - - TMP_DIR = <prefix>/tmp - STAMP_DIR = <prefix>/src/<name>-stamp - DOWNLOAD_DIR = <prefix>/src - SOURCE_DIR = <prefix>/src/<name> - BINARY_DIR = <prefix>/src/<name>-build - INSTALL_DIR = <prefix> - - Otherwise, if the ``EP_BASE`` directory property is set then components - of an external project are stored under the specified base:: - - TMP_DIR = <base>/tmp/<name> - STAMP_DIR = <base>/Stamp/<name> - DOWNLOAD_DIR = <base>/Download/<name> - SOURCE_DIR = <base>/Source/<name> - BINARY_DIR = <base>/Build/<name> - INSTALL_DIR = <base>/Install/<name> - - If no ``PREFIX``, ``EP_PREFIX``, or ``EP_BASE`` is specified then the - default is to set ``PREFIX`` to ``<name>-prefix``. Relative paths are - interpreted with respect to the build directory corresponding to the - source directory in which ``ExternalProject_Add`` is invoked. - - If ``SOURCE_DIR`` is explicitly set to an existing directory the project - will be built from it. Otherwise a download step must be specified - using one of the ``DOWNLOAD_COMMAND``, ``CVS_*``, ``SVN_*``, or ``URL`` - options. The ``URL`` option may refer locally to a directory or source - tarball, or refer to a remote tarball (e.g. ``http://.../src.tgz``). - - If ``UPDATE_DISCONNECTED`` is set, the update step is not executed - automatically when building the main target. The update step can still - be added as a step target and called manually. This is useful if you - want to allow one to build the project when you are disconnected from the - network (you might still need the network for the download step). - This is disabled by default. - The directory property ``EP_UPDATE_DISCONNECTED`` can be used to change - the default value for all the external projects in the current - directory and its subdirectories. - -.. command:: ExternalProject_Add_Step - - The ``ExternalProject_Add_Step`` function adds a custom step to an - external project:: - - ExternalProject_Add_Step(<name> <step> [<option>...]) - - Options are: - - ``COMMAND <cmd>...`` - Command line invoked by this step - ``COMMENT "<text>..."`` - Text printed when step executes - ``DEPENDEES <step>...`` - Steps on which this step depends - ``DEPENDERS <step>...`` - Steps that depend on this step - ``DEPENDS <file>...`` - Files on which this step depends - ``BYPRODUCTS <file>...`` - Files that will be generated by this step but may or may not - have their modification time updated by subsequent builds. - ``ALWAYS 1`` - No stamp file, step always runs - ``EXCLUDE_FROM_MAIN 1`` - Main target does not depend on this step - ``WORKING_DIRECTORY <dir>`` - Working directory for command - ``LOG 1`` - Wrap step in script to log output - ``USES_TERMINAL 1`` - Give the step direct access to the terminal if possible. - - The command line, comment, working directory, and byproducts of every - standard and custom step are processed to replace tokens ``<SOURCE_DIR>``, - ``<BINARY_DIR>``, ``<INSTALL_DIR>``, and ``<TMP_DIR>`` with - corresponding property values. - -Any builtin step that specifies a ``<step>_COMMAND cmd...`` or custom -step that specifies a ``COMMAND cmd...`` may specify additional command -lines using the form ``COMMAND cmd...``. At build time the commands -will be executed in order and aborted if any one fails. For example:: - - ... BUILD_COMMAND make COMMAND echo done ... - -specifies to run ``make`` and then ``echo done`` during the build step. -Whether the current working directory is preserved between commands is -not defined. Behavior of shell operators like ``&&`` is not defined. - -Arguments to ``<step>_COMMAND`` or ``COMMAND`` options may use -:manual:`generator expressions <cmake-generator-expressions(7)>`. - -.. command:: ExternalProject_Get_Property - - The ``ExternalProject_Get_Property`` function retrieves external project - target properties:: - - ExternalProject_Get_Property(<name> [prop1 [prop2 [...]]]) - - It stores property values in variables of the same name. Property - names correspond to the keyword argument names of - ``ExternalProject_Add``. - -.. command:: ExternalProject_Add_StepTargets - - The ``ExternalProject_Add_StepTargets`` function generates custom - targets for the steps listed:: - - ExternalProject_Add_StepTargets(<name> [NO_DEPENDS] [step1 [step2 [...]]]) - -If ``NO_DEPENDS`` is set, the target will not depend on the -dependencies of the complete project. This is usually safe to use for -the download, update, and patch steps that do not require that all the -dependencies are updated and built. Using ``NO_DEPENDS`` for other -of the default steps might break parallel builds, so you should avoid, -it. For custom steps, you should consider whether or not the custom -commands requires that the dependencies are configured, built and -installed. - -If ``STEP_TARGETS`` or ``INDEPENDENT_STEP_TARGETS`` is set then -``ExternalProject_Add_StepTargets`` is automatically called at the end -of matching calls to ``ExternalProject_Add_Step``. Pass -``STEP_TARGETS`` or ``INDEPENDENT_STEP_TARGETS`` explicitly to -individual ``ExternalProject_Add`` calls, or implicitly to all -``ExternalProject_Add`` calls by setting the directory properties -``EP_STEP_TARGETS`` and ``EP_INDEPENDENT_STEP_TARGETS``. The -``INDEPENDENT`` version of the argument and of the property will call -``ExternalProject_Add_StepTargets`` with the ``NO_DEPENDS`` argument. - -If ``STEP_TARGETS`` and ``INDEPENDENT_STEP_TARGETS`` are not set, -clients may still manually call ``ExternalProject_Add_StepTargets`` -after calling ``ExternalProject_Add`` or ``ExternalProject_Add_Step``. - -This functionality is provided to make it easy to drive the steps -independently of each other by specifying targets on build command -lines. For example, you may be submitting to a sub-project based -dashboard, where you want to drive the configure portion of the build, -then submit to the dashboard, followed by the build portion, followed -by tests. If you invoke a custom target that depends on a step -halfway through the step dependency chain, then all the previous steps -will also run to ensure everything is up to date. - -For example, to drive configure, build and test steps independently -for each ``ExternalProject_Add`` call in your project, write the following -line prior to any ``ExternalProject_Add`` calls in your ``CMakeLists.txt`` -file:: - - set_property(DIRECTORY PROPERTY EP_STEP_TARGETS configure build test) - -.. command:: ExternalProject_Add_StepDependencies - - The ``ExternalProject_Add_StepDependencies`` function add some - dependencies for some external project step:: - - ExternalProject_Add_StepDependencies(<name> <step> [target1 [target2 [...]]]) - - This function takes care to set both target and file level - dependencies, and will ensure that parallel builds will not break. - It should be used instead of :command:`add_dependencies()` when adding - a dependency for some of the step targets generated by - ``ExternalProject``. -#]=======================================================================] -
