[CMake] Ctest and setting variables via command line

[ycollette.nospam at free.fr]

Hello,

With the current version of CTest.cmake, it's not possible to set the CTEST_DROP_SITE and some others variables via a cmake command line.
The only solution is to add a CTestConfig.cmake file is the source directory.

What about changing this part of CTest.cmake:

  if(EXISTS "${PROJECT_SOURCE_DIR}/CTestConfig.cmake")
    include("${PROJECT_SOURCE_DIR}/CTestConfig.cmake")
    SET_IF_SET_AND_NOT_SET(NIGHTLY_START_TIME "${CTEST_NIGHTLY_START_TIME}")
    SET_IF_SET_AND_NOT_SET(DROP_METHOD "${CTEST_DROP_METHOD}")
    SET_IF_SET_AND_NOT_SET(DROP_SITE "${CTEST_DROP_SITE}")
    SET_IF_SET_AND_NOT_SET(DROP_SITE_USER "${CTEST_DROP_SITE_USER}")
    SET_IF_SET_AND_NOT_SET(DROP_SITE_PASSWORD "${CTEST_DROP_SITE_PASWORD}")
    SET_IF_SET_AND_NOT_SET(DROP_SITE_MODE "${CTEST_DROP_SITE_MODE}")
    SET_IF_SET_AND_NOT_SET(DROP_LOCATION "${CTEST_DROP_LOCATION}")
    SET_IF_SET_AND_NOT_SET(TRIGGER_SITE "${CTEST_TRIGGER_SITE}")
    SET_IF_SET_AND_NOT_SET(UPDATE_TYPE "${CTEST_UPDATE_TYPE}")
  endif()

into:

  if(EXISTS "${PROJECT_SOURCE_DIR}/CTestConfig.cmake")
    include("${PROJECT_SOURCE_DIR}/CTestConfig.cmake")
  endif()

  SET_IF_SET_AND_NOT_SET(NIGHTLY_START_TIME "${CTEST_NIGHTLY_START_TIME}")
  SET_IF_SET_AND_NOT_SET(DROP_METHOD "${CTEST_DROP_METHOD}")
  SET_IF_SET_AND_NOT_SET(DROP_SITE "${CTEST_DROP_SITE}")
  SET_IF_SET_AND_NOT_SET(DROP_SITE_USER "${CTEST_DROP_SITE_USER}")
  SET_IF_SET_AND_NOT_SET(DROP_SITE_PASSWORD "${CTEST_DROP_SITE_PASWORD}")
  SET_IF_SET_AND_NOT_SET(DROP_SITE_MODE "${CTEST_DROP_SITE_MODE}")
  SET_IF_SET_AND_NOT_SET(DROP_LOCATION "${CTEST_DROP_LOCATION}")
  SET_IF_SET_AND_NOT_SET(TRIGGER_SITE "${CTEST_TRIGGER_SITE}")
  SET_IF_SET_AND_NOT_SET(UPDATE_TYPE "${CTEST_UPDATE_TYPE}")

With such a change we should be able to fine tune some ctest variables via the cmake command line.

Best regards,
