 Following #33259 and r134128 it would be nice if maintainers of ports
 using the cmake PortGroup would add the following line to their ports
 {{{
 cmake.out_of_source yes
 }}}
 and test whether the ports still compile fine (no need for a revbump).
 Some ports already use out-of-source builds, so those ports would need a
 minor clean-up.

 If the port doesn't work that way, please add an explicit
 {{{
 cmake.out_of_source no
 }}}
 with a short comment (and possibly file an upstream bug report).

 Once all the ports are tested, this would become the default behaviour and
 the line (setting `yes`) will be removed from the ports.
