That appears to be a minus for CMake. The build of a library is in my
mind the summation of the build of its separate parts. Being able to
build each part of a library ( the library itself, documentation, tests,
examples etc etc. ) separately must be more flexible than having to
build every part as a whole. In that respect Boost.Build has got it

Boost Build also has a --help option. I do not think a --help option is
sufficient for explaining how something works. I look at the CMake docs
and there is no introduction, no overview, no attempt to explain how the
different parts of the tool relate to each other. While the docs for the
individual pieces of CMake have good explanations I really have to dig
around to understand what I have and how I might want to use it, and I
just don't have that patience. I hate the attitude of programming
documentation that the reader should work hard to figure out basic
things for himself because the documenter is just too lazy to explain
those things in a reasonable clear way.
