I cannot remember that issue.  Also, I checked my bug reports, and I cannot
find anything relevant.

Are you sure it is an issue?  Usual advice; post the simplest possible
example so it is easy for anybody to replicate.

BTW, I had had only one user express dissatisfaction with the new PLplot
CMake-based build system.  His complete focus was the lack of cross-compile
support with CMake as compared to autotools.  Thus, I suspect he may have
just been repeating an anti-CMake rant rather than being serious about
wanting to cross-compile PLplot. Nevertheless, I am really happy you and
Alex are working so hard on the CMake cross-compile issues which is
apparently one of the few weakness of CMake compared to autotools.  (The
only other one I can think of at this time is Fortran.)
