[CMake] How can I instrument code within CMake?

[Mathieu Malaterre]

Hi Fons,

  I have not found any other way than to simple edit the file
CMakeImportBuildSettings.cmake and comment out the following two
lines:

      SET(CMAKE_CXX_COMPILER ${CMAKE_BUILD_SETTING_CXX_COMPILER}
          CACHE STRING "C++ compiler imported from
${CMAKE_BUILD_SETTING_PROJECT_NAME}." FORCE)

  You could also comment out the warning if you want.

HTH
