Linker error during build #1
Description
I get this linker error during building (Ubuntu 18.04 Linux 4.15.0-33 CMake 3.10.2 GNU Make 4.1 GCC 7.3.0)

From some limited searching, I suspect the problem might be that CryptoMiniSat is linked dynamically, but QuAbS is trying to link statically against it, although I do not know whether that's really the case or how to fix it.
