How about languages where there is no separate compiling phase, such as e.g. C#? Is there a placeholder in CMAKE_<LANG>_LINK_EXECUTABLE and CMAKE_<LANG>_CREATE_SHARED_LIBRARY that gets expanded to the list of source files instead of the object files? How to tell CMake to skip the compile-phase without calling "cmake --version" a few thousand times (and creating a lot of bogus output on the screen)?
