Interesting - this indeed fixes the problem, thanks a lot. Attached is a patch
that fixes cmake's official FindKDE3.cmake from cvs accordingly.
The other issues mentioned at
http://www.cmake.org/Bug/bug.php?op=show&bugid=3325&pos=1
are not addressed by this patch. See that bug report for fixes for them.
Anyway I'd like to know why
FIND_PROGRAM(KDE3_DCOPIDL_EXECUTABLE NAME dcopidl)
works at all then. From the docs I'd say find_program should search for a
program named "NAME" now, which of course does not exist.
However if KDE3_DCOPIDL_EXECUTABLE is not set, this call _does_
find /usr/bin/dcopidl, although the "dcopidl" is at a meaningless (according
to the docs) position.
Why is that so?
And why does it behave differently when KDE3_DCOPIDL_EXECUTABLE has been set
to something before?
I'd really like to understand that.
