Currently, the feature checking from Boost.Config has not been implemented
yet, although this could be fix with a simple `check_include_file`.Â
Of course, this is just an initial implementation of the tests in cmake. There
are many areas that need updates from authors, especially since they
understand the test cases better than me. So, any PRs(or feedback) are
welcomed to help improve the tests.

Well we need to know that the cmake modules are sufficient. There are tests
for BCM itself, but this says nothing about how well it will work with boost
libraries.Â
Also, doing this in parallel can help move boost quicker to cmake.

No, apply to all libraries period, as authors of upstream libraries shouldn't
hold back a library from moving to cmake.
