Note for the CMake side this is pretty simple to automate here.  An 
example would be these functions:

 
https://gitlab.com/rleigh/ome-files-cpp/blob/master/cmake/HeaderTest.cmake

which are used here

 
https://gitlab.com/rleigh/ome-files-cpp/blob/master/cmake/HeaderTest.cmake
 
https://gitlab.com/rleigh/ome-files-cpp/blob/master/test/ome-files/CMakeLists.txt#L45

to generate a list of headers to test and then to build and run the 
tests.  This tests both inclusion and double-inclusion to check for ODR 
violations and problems with include guards.

The above were created for a specific project and aren't generic, but an 
equivalent could easily be written for Boost.
