When PARSE_CATCH_TESTS_ADD_TARGET_IN_TEST_NAME is enabled the cmake helper script fails to extract the testcase name if a whitespace is before the name string. Use regex to consider and remove this whitespace.
fix by Mike-Devel
fixes: https://github.com/catchorg/Catch2/issues/1493
If this option is enabled and PARSE_CATCH_TESTS_NO_HIDDEN_TESTS option is disabled, the test is be added, but the DISABLED property is set, therefore CTest shows it as "Not Run (Disabled)" instead of "Passed"
This variable is set to allow the use of the nice ParseAndAddCatchTests script
in the case where a launcher is needed to execute the script.
This is introduced to allow to launch unit tests using mpi. In this case one can
write for instance
set(OptionalCatchTestLauncher ${MPIEXEC} ${MPIEXEC_NUMPROC_FLAG} ${NUMPROC})
before calling the ParseAndAddCatchTests function.
If source files are defined using relative paths, CMake will compile the tests, but this script will (sometimes) fail to find and parse the tests from the source files. I have added an explicit warning when ParseAndAddCatchTests fails to find a source file.
Added cmake script to parse the source files containing Catch's test and generate ctest definitions.
It generates one ctest test per `TEST_CASE` and labels them, using the `TEST_CASE`'s tags.
Closes#719.
