[vtkusers] OSX universal binaires for VTK, cmake , ITK

[Dan White]

Hi Sean,

we just got a new macbookpro with the core duo2 64 bit chip.
we also haver access to a G5

so i wanted to ask you how you have been getting on with building
universal binaires -arch ppc;i386
and also very fat binaries  -arch ppc;ppc64;i386;x86_64
for VTK, CMake etc (we are also building ITK)

Previously i thought there was a problem in CMake that prevented the  
proper generation of universal binaries ppc;i386
because it made the assumption that the build arch was the same as  
the arch for execution of the binaries generated.
So a PPC could make i386 binaries, but they wouldn't run properly?

I might have misunderstood the situation...?
Is this, or was it ever an issue?

Can we just use
CMAKE_OSX_ARCHITECTURES ppc;ppc64;i386;x86_64

or do we have to set the -arch ppc;ppc64;i386;x86_64
in the CFLAGS and CXXFLAGS and linker flags?

any info on the current state of affairs and how to do this the right  
way would be very welcome!

cheers

Dan and the BioImageXD team
