But i don't see the use of the CMAKE_C_COMPILER variable. Setting this seems to have no effect at all. I removed everything related to cmake (except said CMakeList.txt) from my build-tree and my source-tree. *Then* i ran a clean cmake. So i figure the compiler to use can only be set via enviroment vars or by editing CMakeCache.txt after running cmake. (??) But how does this SET( CMAKE_C_COMPILER ....) work? I saw it in several examples on google searching for CMAKE_C_COMPILER.
