Cleanup handling of optional dependencies
Don't use super pedantic parsing of the argument and work with the generated variable instead of assigning it to our own and set it to "check" if not value is assigned. Then search for a dependency if the with variable is anything other than "no" and fail if it was set to "yes". In addition, the WITHOUT_xxx defines are replaced with WITH_xxx defines.
