Improve README for build
The readme for building says
You can remove some by adding
-ENABLE_<COMPONENT>=NO
to the command
That seems to be wrong, it probably needs to be -D ENABLE_<COMPONENT>=NO
The readme says also that doc build is broken for new DOXYGEN versions but does not state how to skip this step. The solution is to pass -D ENABLE_DOC=NO -D ENABLE_CXX_WRAPPER=NO
to the cmake config command.
BTW: I cannot fork and create PRs, I get "Namespace is not valid" from gitlab due to private repo limit.
