Add check for static libraries when compiling CryptoMiniSat #7010 (#7014)

This commit adds a check for CryptoMiniSat's static dependencies when configuring CryptoMiniSat. It changes a build-time failure into a configure-time failure.

`find_library` in CMake > 3.18 supports `REQUIRED`; as `cvc5` targets 3.10, I've implemented a check for what `find_library` returns.
