Compare CMake and old Makefile features

[HomesGH]

There are currently two options to build ls1:

1. Using plain make with the Makefile. This is the old way of building and might be deprecated in the future.
2. Using a build folder and CMake. This is the new and probably preferred option.

In order to remove the first, old Makefile option, it is required to check if all features were migrated.
