Purpose and Motivation
Ccache added support for MSVC in version 4.6.1.
Using it with MSVC requires some additional switches in the CMake which I added.
There's also one "gotcha" - the actual ccache executable, not a chocolatey "shim", needs to be in the PATH for this to work. I've added a note about it in the Windows README
