Despite having a properly configured ccache using $PATH, parts don't seem to be using it when compiling code. It should be automatically picked up and used. A simple test is to build a snap using a simple C++ example. Compiling by hand uses ccache, compiling uses snapcraft doesn't. ``` $ whereis g++ g++: /usr/bin/g++ /usr/lib/ccache/g++ /usr/share/man/man1/g++.1.gz $ which g++ /usr/lib/ccache/g++ ```
