ccache is a clever tool that wraps you compiler (g++ or mpicxx) and understands whether the file you are compiling has been compiled before with exactly the same contents and settings. If it has, it just returns a cached result.

Unlike regular make, ccache is extremely good at detecting the true state of what you are compiling. I have never had any trouble with ccache.

This really speeds up the compilation when you are using make clean, especially if you are switching git branches. In other words, it is a much simpler solution to achieve fast compilation with git branches than to create separate build folders for each branch.

To enable ccache, install it with

sudo apt-get install ccache
and add the following to your .pro file:
