[CMake] Activating coverage with ctest

[ANTON DEGUET]

Thanks to both you and Xavier,

I had seen this FAQ but I was wandering if there was a way to have this somewhat automated using CMake.  I played a bit with my DartConfig.cmake and I now have:
IF(CMAKE_COMPILER_IS_GNUCXX)
  SET(CTEST_COVERAGE_COMMAND ${COVERAGE_COMMAND})
  SET(CMAKE_C_FLAGS_DEBUG "${CMAKE_C_FLAGS_DEBUG} -ftest-coverage -fprofile-arcs")
  SET(CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG} -ftest-coverage -fprofile-arcs")
  SET(CMAKE_EXE_LINKER_FLAGS_DEBUG "${CMAKE_EXE_LINKER_FLAGS_DEBUG} -ftest-coverage -fprofile-arcs")
  LINK_LIBRARIES(gcov)
ENDIF(CMAKE_COMPILER_IS_GNUCXX)

This seems to work but I have a few pending questions:

-1- Does this make any sense anyway?

-2- In the FAQ, you don't have a linker option to specify -lgcov.  Is this normal?

-3- The tests seem much slower.  Before I dig in the gcc documentation, is this to be expected?

-4- This one should probably be in a different thread, but if I try to build a shared library on Mac OS X using the makefile generator I get the following error:
ld: common symbols not allowed with MH_DYLIB output format with the -multi_module option
/usr/lib/gcc/powerpc-apple-darwin8/4.0.1/libgcov.a(_gcov.o) definition of common ___gcov_var (size 4128)
/usr/bin/libtool: internal link edit command failed
Any clue?

Anton
