dit(bf(CCACHE_SWIG)) The CCACHE_SWIG environment variable needs to be
set in order for ccache to work with SWIG. Currently the CCACHE_CPP2
environment variable also needs to be set in order to work with SWIG.
dit(bf(CCACHE_SWIG)) When using SWIG as the compiler and it does not
have 'swig' in the executable name, then the CCACHE_SWIG environment
variable needs to be set in order for ccache to work correctly with
SWIG.
