This project allows you to cache the compilation on Unreal Engine building (like ccache).
It’s supported out of box (you need simply install it):
Visual Studio UBT build on Windows
clang UBT build on Linux
It speeds up recompilation by caching previous compilations and detecting when the same compilation is being done again.
You can get configuration files and show default and actual configuration by running
On Windows you can’t mix compilation with and without octobuild.
