``CMAKE_ARGS <arg>...``
Arguments to CMake command line.
These arguments are passed to CMake command line, and can contain
arguments other than cache values, see also
:manual:`CMake Options <cmake(1)>`. Arguments in the form
``-Dvar:string=on`` are always passed to the command line, and
therefore cannot be changed by the user.
Arguments may use
:manual:`generator expressions <cmake-generator-expressions(7)>`.
``CMAKE_CACHE_ARGS <arg>...``
Initial cache arguments, of the form ``-Dvar:string=on``.
These arguments are written in a pre-load a script that populates
CMake cache, see also :manual:`cmake -C <cmake(1)>`. This allows one to
overcome command line length limits.
These arguments are :command:`set` using the ``FORCE`` argument,
and therefore cannot be changed by the user.
Arguments may use
:manual:`generator expressions <cmake-generator-expressions(7)>`.
``CMAKE_CACHE_DEFAULT_ARGS <arg>...``
Initial default cache arguments, of the form ``-Dvar:string=on``.
These arguments are written in a pre-load a script that populates
CMake cache, see also :manual:`cmake -C <cmake(1)>`. This allows one to
overcome command line length limits.
These arguments can be used as default value that will be set if no
previous value is found in the cache, and that the user can change
later.
Arguments may use
:manual:`generator expressions <cmake-generator-expressions(7)>`.
Build step options are:
``BINARY_DIR <dir>``
Specify build dir location
``BUILD_COMMAND <cmd>...``
Command to drive the native build
``BUILD_IN_SOURCE 1``
Use source dir for build dir
``BUILD_ALWAYS 1``
No stamp file, build step always runs
``BUILD_BYPRODUCTS <file>...``
Files that will be generated by the build command but may or may
not have their modification time updated by subsequent builds.
Install step options are:
``INSTALL_DIR <dir>``
Installation prefix
``INSTALL_COMMAND <cmd>...``
Command to drive install after build
Test step options are:
``TEST_BEFORE_INSTALL 1``
Add test step executed before install step
``TEST_AFTER_INSTALL 1``
Add test step executed after install step
``TEST_EXCLUDE_FROM_MAIN 1``
Main target does not depend on the test step
``TEST_COMMAND <cmd>...``
Command to drive test
Output logging options are:
``LOG_DOWNLOAD 1``
Wrap download in script to log output
``LOG_UPDATE 1``
Wrap update in script to log output
``LOG_CONFIGURE 1``
Wrap configure in script to log output
``LOG_BUILD 1``
Wrap build in script to log output
``LOG_TEST 1``
Wrap test in script to log output
``LOG_INSTALL 1``
Wrap install in script to log output
Steps can be given direct access to the terminal if possible. 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``.
