Hi Benedikt, interesting thought, however I wonder why cmake is then capable of deducing the right boost version and include path. Just inside the first error message, I see: (x86)/CMake/share/cmake-3.2/Modules/FindBoost.cmake:1182 (message): > > Unable to find the requested Boost libraries. > > > > Boost version: 1.57.0 > > > > Boost include path: C:/msys64/mingw64/include > > > > Could not find the following static Boost libraries: > > boost_filesystem > > boost_system
