It appears that the packagers of the Xcode 7 application GM release got confused by the recent Xcode 6.3 and 6.4 releases which only supported a single OS X release and neglected to include the 10.10 SDK. Since Xcode 7 GM runs on both Yosemite and El Capitan, it must provide both SDKs like Xcode 6.2 did for Mavericks and Yosemite. Curently Command_Line_Tools_OS_X_10.10_for_Xcode_7_GM_seed.dmg contains Command Line Tools (OS 10.10).pkg which in turn contains DevSDK_OSX1010.pkg. This creates a rupture on 10.10 between the SDK used for the headers in /usr/include and the only SDK available in Xcode.app itself.

Currently the only solution is to manually copy over the missing MacOSX10.10.sdk from the Xcode 6.4 release.

Apparently this is by design. Fortunately for cmake builds this mismatched SDKs can be avoid by using...

-DCMAKE_OSX_DEPLOYMENT_TARGET:STRING="" \

-DCMAKE_OSX_SYSROOT:STRING=/ \

to keep cmake away from the buried SDK in Xcode.app. This also avoids the associated warnings from cmake...

CMake Warning at /sw/share/cmake-3.3/Modules/Platform/Darwin-Initialize.cmake:97 (message):

CMAKE_OSX_DEPLOYMENT_TARGET is '10.10' but the matching SDK does not exist

at:

"/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk"

Instead using SDK:

"/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk".

Is the Deployment Target set to 10.10 in both the Project and the Target? I've noticed that in some of my projects changing one doesn't change the other.
