I want to be able to extract this cut-down tree on demand, including
modifications to the CMakeLists.txt (and a few other places) to
remove
references to removed files. I need to do this for a variety of
licensing and quality-audit reasons. Just adding some option to my
CMakeLists.txt files to exclude files from the compilation will not

enough.
This sounds scary.
I would solve this problem with SCM tools. For example, you could
cut a
branch for your pared-down project, delete the unwanted files and
modify
the CMakeLists on that branch, and Bob's your uncle. This approach
requires you to use merging to keep your branch up-to-date, but to me
that seems less onerous than having a script that tweaks your build
scripts every time.

Boost solved this with a custom program called "bcp". Bcp scans the
headers for #include <boost/*> and then copies the include files and
implementation files into the new location. Not that I am advocating
that type of solution but in the case of boost, it did work.
I was able to extract out a portion of boost for what I use with my
own projects which cut boost down to just a few hundred files, instead
of the whole enchilada.
