User:Mattx86/qwn:Enabling ccache

"ccache is a compiler cache. It speeds up recompilation by caching previous compilations and detecting when the same compilation is being done again. Supported languages are C, C++, Objective-C and Objective-C++."

To enable ccache, first install ccache:

apk add ccache

Next, add it to your path by placing the following in your ~/.profile (ash) or ~/.bash_profile (bash).

export PATH="/usr/lib/ccache/bin:$PATH"
