        2. :py:meth:`~.CMakePackage.build`
        3. :py:meth:`~.CMakePackage.install`

    For a finer tuning you may also override:

    The generator used by CMake can be specified by providing the
    generator attribute. Per
    https://cmake.org/cmake/help/git-master/manual/cmake-generators.7.html,
    the format is: [<secondary-generator> - ]<primary_generator>. The
    full list of primary and secondary generators supported by CMake may
    be found in the documentation for the version of CMake used;
    however, at this time Spack supports only the primary generators
    "Unix Makefiles" and "Ninja." Spack's CMake support is agnostic with
    respect to primary generators. Spack will generate a runtime error
    if the generator string does not follow the prescribed format, or if
    the primary generator is not supported.
