My apologies if this is not the correct forum;
This is being done to make it more compatible with other CMake builds, specifically including Google's OR Tools. It would be great if this work could be included in the official codebase, or if anyone could lend a hand in testing and/or ironing out any potential bugs.
One of the benefits of this CMake effort is that there is no need to maintain a separate build script for MSCV, as it builds and runs great on MSVC using CMake - this may be of interest to the maintainers of GLPK.
Kind regards,
Kyle
