That's why I've been prototyping CMake configuration for Boost.GIL that
should allow contributors to use reasonably new Boost installed system-wide
from binary distribution, then `git pull boostorg/gil` only and
be able to develop.

Might be. TBH, I'm not able to clarify myself what bit of the docs
belongs to where.

However, using CMake-based knowledge,
for general CMake options I go to;
for a project specific build options, I refer to
But, I know that the former start with CMAKE_ prefix and that small
detail is extremely important to get my bearings right.

I see no conventions or patterns, no no-brainers to learn.

Why not allow intrinsic b2 properties as options

b2 --toolset=gcc --variant=debug

while all project/configuration-specific can only be given as

b2 --property foo=bar
b2 -p foo=bar

or something like that.
