[CMake] Build doesn't work with Mac OS X Lion...

Hi,
And which one is which?
In Xcode (4.2), Lion, 64 bit Intel platform, a standard Xcode Mac OS X "template" will give these build settings in the Architectures section:
Architectures
Additional SDKs
Architectures 64-bit Intel - $(ARCHS_STANDARD_64_BIT) (this last value is grayed out)
Base SDK Latest Mac OS X (Mac OS X 10.7)
Build Active Architecture Only <Multiple values>
Supported Platforms macosx
Valid Architectures i386 x86_64
I always thought that the CMAKE_OSX_ARCHITECTURES value corresponded with the "first" Architectures Xcode field. So I set:
set(CMAKE_OSX_ARCHITECTURES "$(ARCHS_STANDARD_64_BIT)") in my CMake builds.
But with your last mail i'm confused if it corresponds to the Valid Architectures field instead.
Or are these fields related? 64-bit Intel *implies* i386 and x86_64, although you could remove one of the two.
For an iOS "template" on the same system I get this:
Architectures
Additional SDKs
Architectures Standard (armv7) - $(ARCHS_STANDARD_32_BIT) (this last value is grayed out)
Base SDK /Developer/[blabla]/iPhoneOS5.0.sdk
Build Active Architecture Only No
Supported Platforms iphonesimulator iphoneos
Valid Architectures armv6 armv7
Thanks,
Daniel
