Really ?
We use a lot of custom commands in KDE, all the time, everywhere, and people 
build KDE on big build clusters, i.e. very parallel, without problems.

Maybe there are problems when multiple targets depend on the same generated 
file, but I think the "cmake inherently has problems with parallel builds when 
custom targets/commands come into play." is wrong in this very generic way.
