[CMake] cmake on Snow Leopard

[Michael Jackson]

_CMake_ isn't the one building the 32 bit binaries, 10.6 is building  
them by default. You either have to rebuild all your support libraries  
as 64 bit or Universal binaries, or figure out how to get your project  
to build for 32 bit by supplying the CMAKE_OSX_ARCHITECTURES=i386.

  You might want to try starting from an empty build directory then  
invoking cmake like the following:

cmake -DCMAKE_OSX_ARCHITECTURES=i386 ../

Failing that, you can try this:

export CXXFLAGS="-arch i386"
export CFLAGS="-arch i386"

the invoking CMake on an empty build directory again.

Just some thoughts. I don't have 10.6 yet so I am left guessing at  
this point..
