Is there a way to continue a partially finished MinGW build?

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.

Try adding the -k install flag, ie:

make -k install

when generating the make file.

=====================

Based on our discussion below:

• What you're asking for is not possible afaik. Make style build systems are designed to fail on error - the "no partial installs policy". If a build doesn't complete 100%, the system aborts.
• Makefile creators are expected to inspect each dependency and decide, for each one individually, whether it's a definite or optional requirement.
