The CXX Driver equivalent of changes in mongodb/mongo-c-driver#1522. Verified by this patch.
The only caveat is that the CXX Driver does not have its own ccache detect-and-use routine a la CCache.cmake in the C Driver, so each instance of setting the ccache environment variables is preceeded by a test for
ccachebeing present.For consistency, other instances of the ccache test have been changed to use the same
command -Vmethod, which prints the path to the ccache binary when present in an informative manner (e.g.ccache is /usr/bin/ccache) in lieu of the explicit message that was being used prior.
