No rule to make target 'libs/src/BoehmGC-build/./gcmt-dll.lib' (MinGW-w64)

I'm trying to build NekoVM from source, as the Windows binaries provided seem to be built with MSVC, whilst my team uses MinGW-w64. However, in the build step, I eventually get this error message:

> **mingw32-make.exe[2]: \*\*\* No rule to make target 'libs/src/BoehmGC-build/./gcmt-dll.lib', needed by 'bin/libneko.dll'. Stop.
mingw32-make.exe[1]: \*\*\* [CMakeFiles\Makefile2:404: CMakeFiles/libneko.dir/all] Error 2
mingw32-make.exe: \*\*\* [Makefile:162: all] Error 2**

I would say I'm familiar enough with building and using libraries, but I'm not really sure what to do to fix this. I have tried to build both from MSYS + MinGW and standalone MinGW (from Windows terminal), same output in both cases. Any clue on why this happens? Thank you very much.

(The toolkit I'm using is MinGW-w64 **i686-posix-dwarf-rev0**, with Make v**4.2.1** and GCC v**8.1.0**)
