A compiler cache speeds up compilation times by caching object files and reusing them on subsequent builds. This even works for complete rebuilds (i.e. deleting the full build-directory). The compiler cache ccache is automatically used when it is found by CMake.
Install it with your package manager, e.g.:
sudo apt install ccache
Just load the module:
module load /global/apps/modulefiles/ccache/3.3.3
brew install ccache
Windows support in ccache is not yet in the main ccache development line. Please install ccache from https://github.com/cristianadam/ccache/releases.
Just extract the archive and put the ccache.exe into the PATH.
You may want to change the cache directory (environment variable CCACHE_DIR) or increase the cache size (e.g. ccache -M 10G or CCACHE_MAXSIZE). See the ccache docs for configuration instructions.
You can check cache hit statistics with ccache -s.
To disable caching:
cmake . -DOGS_DISABLE_COMPILER_CACHE=ON
