# Don't try to create universal binaries on Mac OS X, as this causes compilation problems.

# On Darwin, the CMakeDetermineSystem.cmake module sets system processor values
# using 'uname -p'.  On Intel Macs, at least, this always returns "i386" which
# is technically not what we want. We want 'uname -m' which returns the machine
# architecture.  On 64-bit architectures this is the value we want for "host" builds.
