[CMake] Adding to RUN_TESTS target

[David Cole]

Just run ctest down in the sub-directory, any directory with a
"CTestTestfile.cmake" file in it, (run it with no arguments), and it
will run the tests in that directory.

With Visual Studio, you'll need to use "${CMAKE_CTEST_COMMAND} -C
${CMAKE_CFG_INTDIR}" as the custom command to get the tests to run for
the right configuration.

I would do something like this if I were going to do it:

add_custom_command(OUTPUT ${CMAKE_BINARY_DIR}/SubdirTests.log
  ${CMAKE_CTEST_COMMAND} -C ${CMAKE_CFG_INTDIR} -O
${CMAKE_BINARY_DIR}/SubdirTests.log
  WORKING_DIRECTORY ${CMAKE_BINARY_DIR}/Subdir
)

add_custom_target(SubdirTests DEPENDS ${CMAKE_BINARY_DIR}/SubdirTests.log)

Then you could build the "SubdirTests" target to run the tests.

Of course, if you need to extend the subset, you could run a script as
the "test suite" instead, and in the script, do your pre-stuff, run
the ctest tests with the same command as above, and then do your
post-stuff.


Cheers,
David
