[CMake] How to pass a configuration file to CMake?

[Petr Kmoch]

Hi Cedric.

I believe the comment string argument is mandatory in a set(... CACHE), so
it should be something like this:

set(ENABLE_DOWNLOAD True CACHE BOOL "Should download be enabled")
set(GCC_ROOT "/local/cdoucet/gcc/4.9.2/" CACHE PATH "Path to root directory
of GCC installation")
