How is that different? Do you mean to drop the PROJECT_VERSION_{...}
entirely? That doesn't seem desirable for symmetry with the other
PROJECT_{...} variables.
I think I'm with Brad; set the PROJECT_VERSION_{...} and
${PROJECT_NAME}_VERSION_{...} (note; no extra literal 'PROJECT') as
usual. Always. Whether or not VERSION was specified (i.e. unset the
corresponding variables in such case).
Folks that use the PROJECT_{...} forms hopefully know what they are
doing, otherwise people are hopefully using the ${PROJECT_NAME}_{...}
forms instead.
Related: Do these affect the version properties of libraries? (Because
OTOH if it does, I can imagine wanting to say VERSION once at the root
and have it inherit downwards unless overridden. Maybe though that's a
reason for it to not do so.)
