# CTestUseLaunchers
# -----------------
#
# Set the RULE_LAUNCH_* global properties when CTEST_USE_LAUNCHERS is on.
#
# CTestUseLaunchers is automatically included when you include(CTest).
# However, it is split out into its own module file so projects can use
# the CTEST_USE_LAUNCHERS functionality independently.
#
# To use launchers, set CTEST_USE_LAUNCHERS to ON in a ctest -S
# dashboard script, and then also set it in the cache of the configured
# project.  Both cmake and ctest need to know the value of it for the
# launchers to work properly.  CMake needs to know in order to generate
# proper build rules, and ctest, in order to produce the proper error
# and warning analysis.
#
# For convenience, you may set the ENV variable
# CTEST_USE_LAUNCHERS_DEFAULT in your ctest -S script, too.  Then, as
# long as your CMakeLists uses include(CTest) or
# include(CTestUseLaunchers), it will use the value of the ENV variable
# to initialize a CTEST_USE_LAUNCHERS cache variable.  This cache
# variable initialization only occurs if CTEST_USE_LAUNCHERS is not
# already defined.
