That's an issue with our own build system and not CMake.  From time to
time we try and clean up some aspect of this issue, but it is a low
priority because it is so easy to use PATH's without spaces in them.

Are you using PLplot-5.10.0 or the git master tip version (which is
about to turn into PLplot-5.11.0)?  I would prefer you to try the
master tip version if you haven't been doing that already because it
has been a very long time since 5.10.0 was released, I am much more
familiar with the master tip version, and I would like to get the
master tip version tested as well as possible before the 5.11.0
release.  For example, if you spot a USINGDLL issue for that version
(such as USINGDLL being defined for the static library case), please
let me know with lots of details.
