How to Use CCache with CMake?

Answer 1

I verified the following works (source: this link):

        CC="gcc" CXX="g++" cmake -D CMAKE_CXX_COMPILER="ccache" -D CMAKE_CXX_COMPILER_ARG1="g++" -D CMAKE_C_COMPILER="ccache" -D CMAKE_C_COMPILER_ARG1="gcc" $*

Update: I later realized that even this does not work. Strangely it works every alternate time (the other times cmake complains).
