[CMake] cmake+insure (or purify)

[AKHRES Nader]

Hi all,

I'd like to use insure (or purify) for my project using cmake.
Problematic is that you use 'insure gcc' instead of gcc for compilation 
and 'insure ld'/'insure gcc' for linking.
I manage to make cmake take into account insure gcc for compilation but 
unfortunately I don't know how to choose the linker...

Any ideas?

ps: CMAKE_CXX_LINKER_EXECUTABLE don't work for me
