That isn't really an issue so long as people are building under Cygwin
or MSys/MinGW, as the build directory will probably be within the Unix

Personally, I consider "best practice" to be not cluttering up the
Makefiles with lots of quotes. Just take the same approach as every
other Unix project in existence, and require the build directory to
have a "sane" pathname.

Supporting spaces or other metacharacters in the pathname to the final
installation directory would be reasonable, and probably not much work
as it's only really relevant to the "install" target in the top-level
