CMake is a widely used build system and has become for many the de facto standard. Boost is a widely used collection of modules and has become for many part of the de facto standard. However, the two do not play very well together. I know there is another port of boost to CMake, but it has lain dormant for years and uses an old version of boost; plus I chose to take a different route. The old project attempted to completely replace Boost.Build with CMake. My example port simply allows people to more easily use boost modules in their projects. I created an example project https://github.com/Elzair/cmake-boost-filesystem-test to demonstrate my ideas. I added CMake build support to the minimum number of modules needed to support this demo: https://github.com/Elzair/assert https://github.com/Elzair/config https://github.com/Elzair/core https://github.com/Elzair/filesystem/tree/master and https://github.com/Elzair/system I even added CMake build support to the header only boost libraries. I did this for two reasons. First, I did not want users to have to fool with CMake's find_package(). Second, I wanted to add helpful error messages in case a user has not included all of a module's dependencies (or added them in the wrong order). Would the community be interested in modular CMake support for more modules? Any comments, questions, critiques or suggestions are welcome.
