It turns out those Windows issues have all been largely resolved so I
adjusted build_projects (revision 12379) to work properly with ninja,
and I have obtained some quite interesting results with that build
tool.  It really is faster than gmake (by a small amount on Linux and
by roughly a factor of two to four on Windows).  Even more important
than the efficiency question is that ninja is designed from the top to
be configured by a programme (such as CMake) rather than by humans.
So as well as having a lot less baggage than gmake it also diagnoses
build configuration issues produced by CMake much better then gmake
does.  For more details about this aspect of ninja as well as its
build efficiency, please consult a post I just made to the CMake
mailing list concerning the build_projects project and ninja.
