I'm also using git and cmake and I use ccache to solve this problem.
When building after switching branch if you did not change anything
ccache hits the cache. I know ccache works well with gcc or mingw but
for other compiler I don't know. Maybe it is possible to use it only
with the Makefile generator of cmake.
