As of Xcode 4.3, SDKs are not located in /Developer anymore, but that is the location indigo hardcodes in common/cmake/MacFrameworks.cmake and common/cmake/SetBuildParameters.cmake; that needs to be fixed.

cmake already provides mechanisms to learn the SDK path; projects like indigo don't need to do so manually. At least, I found code to do so in /opt/local/share/cmake-2.8/Modules/Platform/Darwin.cmake. I don't know cmake so I don't know how indigo can access that code.
