The environment variable `CXX` can be used to control the C++ compiler used, or
run one of the following:
$ make config-clang
$ make config-gcc
Note that these will result in `make` ignoring the `CXX` environment variable,
unless `CXX` is assigned in the call to make, e.g.
$ make CXX=$CXX
For other compilers and build configurations it might be
necessary to make some changes to the config section of the
Makefile.
