CMake improvements
- Use cmake-library GMM finder instead of old CoMISo finder (+adjust CI for this); use CMake targets for GMM
- Use CMake target existence for Gurobi (fixed some issue I had with a reconfigure)
- Allow disabling some dependencies using default-enabled
COMISO_ENABLE_*
options. - Let the user choose if they want to build a static or shared library via
BUILD_SHARED_LIBS
