I don't know if it's already possible or not but I would be very interested
in the feature too. Helping user to use the build system is of
great interest.

I think I would be useful to have the exact CMake command line

1) as a comment inside CMakeCache.txt
2) as a CMake string var something like:
    CMAKE_COMMAND_LINE

Note that may be  CMAKE_COMMAND_LINE should indicate
what CMake tool was used: cmake, CMakeSetup, ccmake etc...

Should on of us file a feature request?
