(1) http://public.kitware.com/Bug/view.php?id=10718 is fixed. In my
view this bug has been the source of much CMake find trouble for a long
time, and I hope the CMake developers make it a high priority to fix
it for CMake-2.8.3.
If I understand correctly, the intention of 10718 is to denote possibly
non-equivalent alternatives after NAMES and use the super-path to pick
out one of them.
Correct. This issue has come up several times on the PLplot developer
list in several contexts (not only Python). Without the fix, it
proves impossible to manipulate the super-PATH to allow CMake to find
anything later in the NAMES list (normally a lower version) if
something earlier (normally a higher version) exists anywhere in the
super-PATH on your system. The fix to 10718 is to swap the inner and
outer loops in the CMake code so super-PATH order takes precedence
over NAMES order.
I believe that solution of 10718 will make life easier for Find module
maintainers and developers. Which is why I brought it up in
connection with this thread. However, I don't want to
over-concentrate on this one matter at the expense of the rest of this
important topic which is how to improve the Python Find module. So
that is probably enough about 10718 for now.
