Hi,
I checked and in Darwin.cmake there are several items like
"CMAKE_OSX_ARCHITECTURES_DEFAULT" and
"CMAKE_OSX_DEPLOYMENT_TARGET_DEFAULT"... But...
I can't set them properly in my own CMakeLists.txt file. As such,
when I set
the minimum version to 10.4, it still will try to compile against
v10.5 of
the SDK...
Is there a way to set all of this properly or do I need to fiddle
with the
C/CXX make flags (bah)?
Thanks,
Steven
The variables are CMAKE_OSX_ARCHITECTURES,
CMAKE_OSX_DEPLOYMENT_TARGET and CMAKE_OSX_SYSROOT. The ones you
mentioned are the defaults to pre-populate the cache and get
assigned to the variables I mentioned before you have any chance of
changing them.
However, I strongly advice NOT to set them in your CMakeLists.txt,
unless it really is required. Let the user set those variables in
the cache.

I Would also add that by setting the SDK Root to 10.4 you are
basically saying that your code ONLY runs on 10.4 and NOT 10.5. Is
that really what you want?
http://public.kitware.com/Bug/view.php?id=6195 has a good history
and proper usage of those variables.
If you _really_ wand to set those then you will probably have use the
long form of the "set()" command with the keyword "FORCE" but I
encourage you to read through the bug report to figure out if this is
truly what you want.
