I am opposed to this, and what we are proposing is allowing Cmake at the
top-level. I have yet to see a technical issue with this. It is true that
the cmake is more prominent then the bjam, but it is also better supported
for those libraries that put CMakeLists.txt at the top-level. Boost.Hana,
for example, has a more extensive test-suite when using cmake.
