# Usage #
# 1. make sure this module is in the path or add this otherwise: #
# set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_SOURCE_DIR}/cmake.modules/") #
# 2. make sure that you've enabled testing option for the project by the call: #
# enable_testing() #
# 3. add the lines to the script for testing target (sample CMakeLists.txt): #
# project(testing_target) #
# set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_SOURCE_DIR}/cmake.modules/") #
# enable_testing() #

# add_executable(${PROJECT_NAME} ${SOURCE_FILES}) #

# The following variables affect the behavior of the script: #
# #
# PARSE_CATCH_TESTS_VERBOSE (Default OFF) #
# -- enables debug messages #
# PARSE_CATCH_TESTS_NO_HIDDEN_TESTS (Default OFF) #
# -- excludes tests marked with [!hide], [.] or [.foo] tags #
# PARSE_CATCH_TESTS_ADD_FIXTURE_IN_TEST_NAME (Default ON) #
# -- adds fixture class name to the test name #
# PARSE_CATCH_TESTS_ADD_TARGET_IN_TEST_NAME (Default ON) #
# -- adds cmake target name to the test name #
# PARSE_CATCH_TESTS_ADD_TO_CONFIGURE_DEPENDS (Default OFF) #
# -- causes CMake to rerun when file with tests changes so that new tests will be discovered #
# #
# One can also set (locally) the optional variable OptionalCatchTestLauncher to precise the way #
# a test should be run. For instance to use test MPI, one can write #
# set(OptionalCatchTestLauncher ${MPIEXEC} ${MPIEXEC_NUMPROC_FLAG} ${NUMPROC}) #
# just before calling this ParseAndAddCatchTests function #
# #
# The AdditionalCatchParameters optional variable can be used to pass extra argument to the test #
# command. For example, to include successful tests in the output, one can write #
# set(AdditionalCatchParameters --success) #
# #
# After the script, the ParseAndAddCatchTests_TESTS property for the target, and for each source #
# file in the target is set, and contains the list of the tests extracted from that target, or #
# from that file. This is useful, for example to add further labels or properties to the tests. #
