I am just trying to become familiar with MinGW (and with more complex command-line compiler tools)

I have a really giant project to build, I successfully managed to generate the makefile with CMake, and started mingw.

After more than an hour of hard work, and building dozens of libraries successfully, the build ended in an error. It seems I added an option in CMake which is not supported in my system. My problem is, I cannot figure out a way to just skip that library and continue with the build process. If I remove the option in CMake and start mingw again, it starts from the beginning and rebuilds everything, even those libraries which are already built.
