What problems do you see with your own compiler cache that makes you consider
using ccache instead?

Does your compiler behave similar to GCC, for instance using "-c" for
compilation, "-E" for generating preprocessed output similar to that of GCC,
"-x" for selecting source language, etc? If not, my guess is that it's not
really feasible.

There is no documentation or examples for adding new compiler support to
ccache, mainly because ccache in a sense only supports one ("GCC and compilers
that behave similar enough").
