ExternalProject handles git remote branches by commit hash. Due to this, the git repository ends in detached states, and local commits are discarded. Use "git rebase" for remote branches instead of "git checkout". If there are uncommitted changes, use "git stash save/pop" to save changes and restore them after the rebase. If any of these operations fails, try to restore the original status and exit with a fatal error, asking the user to resolve the conflicts manually. This also makes the behaviour of ExternalProject using git more similar to the svn version, and probably more likely to what the user expects by setting GIT_TAG to a branch.

# Create custom targets to build projects in external trees

|
|
# The ``ExternalProject_Add`` function creates a custom target to drive

|
|
#
|
|
# 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``).
|
|
#
|
|
# The ``ExternalProject_Add_Step`` function adds a custom step to an
|
|
# external project:
|
|
#
|
|
# .. code-block:: cmake
|
|
#
|
|
# ExternalProject_Add_Step(<name> <step> # Names of project and custom step
|
|
# [COMMAND cmd...] # Command line invoked by this step
|
|
# [COMMENT "text..."] # Text printed when step executes
|
|
# [DEPENDEES steps...] # Steps on which this step depends
|
|
# [DEPENDERS steps...] # Steps that depend on this step
|
|
# [DEPENDS files...] # Files on which this step depends
|
|
# [ALWAYS 1] # No stamp file, step always runs
|
|
# [WORKING_DIRECTORY dir] # Working directory for command
|
|
# [LOG 1] # Wrap step in script to log output
|
|
# )
|
|
#
|
|
# The command line, comment, and working directory of every standard and
|
|
# custom step is 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.
|
|
#
|
|
# 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``.
|
|
#
|
|
# The ``ExternalProject_Add_StepTargets`` function generates custom
|
|
# targets for the steps listed::
|
|
#
|
|
# ExternalProject_Add_StepTargets(<name> [step1 [step2 [...]]])
|
|
#
|
|
# If ``STEP_TARGETS`` is set then ``ExternalProject_Add_StepTargets`` is
|
|
# automatically called at the end of matching calls to
|
|
# ``ExternalProject_Add_Step``. Pass ``STEP_TARGETS`` explicitly to
|
|
# individual ``ExternalProject_Add`` calls, or implicitly to all
|
|
# ``ExternalProject_Add`` calls by setting the directory property
|
|
# ``EP_STEP_TARGETS``.
|
|
#
|
|
# If ``STEP_TARGETS`` is 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)
