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). A compiler cache is automatically used when it is found by CMake.
For Linux and macOS you can use ccache. You may want to change the cache directory (environment variable CCACHE_DIR) or increase the cache size (CCACHE_MAXSIZE). See the ccache docs for configuration instructions.
You can check cache hits with ccache -s.
Just load the module:
module load /global/apps/modulefiles/ccache/3.3.3
See Linux-tab!
On Windows you can use clcache. Install it with Chocolatey:
curl -L https://github.com/frerich/clcache/releases/download/v4.2.0/clcache.4.2.0.nupkg --output clcache.4.2.0.nupkg
choco install clcache --source=.
You may want to increase the cache size (to 10 GB in this case):
clcache -M 10000000000
You can check cache hits with clcache -s.
To disable caching:
cmake . -DOGS_DISABLE_COMPILER_CACHE=ON
