I don't want to set the value to architecture set to i386 when I'm
building on a PowerPC system. I also only want a single architecture
for a debug build and universal binary for release builds.
So, I tried doing this in a section of the CMake script that already
determined it was building on Mac OS X:
if(CMAKE_SYSTEM_PROCESSOR MATCHES "i386")
set(OSX_ARCHITECTURES_DEBUG "i386")
endif(CMAKE_SYSTEM_PROCESSOR MATCHES "i386")
However when I go to build a debug target in the project the build
output indicates that the "-arch x86_64" flag is in use, causing the
built executable to be 64-bit.
The command:
cmake --help-property OSX_ARCHITECTURES
mentioned something about the CMAKE_OSX_ARCHITECTURES variable, however
the command:
cmake --help-variable CMAKE_OSX_ARCHITECTURES
complained that CMAKE_OSX_ARCHITECTURES was not a defined variable.
What needs to be applied to get CMake to configure a Snow Leopard system
as 32-bit?

I am writing a cross platform application using CMake that builds on
Mac OS X. I just upgraded to CMake 2.8-1. When I configure and
build my project on my Power Mac G5 system running Mac OS X 10.5.8,
the project builds just fine.
When I try to configure the project on my MacBook Pro running Mac OS
X 10.6.3, I get link errors because the project has been configured
to build 64-bit applications and some of the needed libraries and
frameworks the project links with are only 32-bit.
How can I configure my CMake scripts so that the project will build
a 32-bit application on my MacBook Pro?
