Sebastian Bøe 709daa20e9 cmake: Find a directory that could be used to cache files ... To improve the build system's "clean build" runtime we need to cache files in a directory outside of the build directory. Caching files outside of the build directory is is already being done to a certain degree today. For instance, if a user has installed ccache it will cache files in $HOME/.ccache/. This commit locates a directory that is suitable for caching files in a cross-platform way. For instance on Linux this is believed to be $HOME, on Windows this is believed to be %LOCALAPPDATA%. If for whatever reason no environment variables are are found to be suitable we fall back to using $ZEPHYR_BASE/.cache/. For users that often use 'git -clean' the caching mechanism will not work as well, but it will at least be better than no caching at all.
