CMake broken after update to Xcode 7.0

Question

I use QtCreator and CMake for c++ development on a Mac, after updating to Xcode 7.0, CMake seems broken, after running CMake I got this warning:

CMake Warning at /usr/local/Cellar/cmake/HEAD/share/cmake/Modules/Platform/Darwin-Initialize.cmake:128 (message): Ignoring CMAKE_OSX_SYSROOT value:

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

because the directory does not exist. Call Stack (most recent call first): /usr/local/Cellar/cmake/HEAD/share/cmake/Modules/CMakeSystemSpecificInitialize.cmake:18 (include) CMakeLists.txt:3 (project)

and build, I got this error:

*** No rule to make target `/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/System/Library/Frameworks/Accelerate.framework'

I know that Xcode 7.0 has removed MacOSX10.10.sdk and added MacOSX10.11.sdk, so I thought it might be my cmake is too old, I updated my cmake to 3.3.2 with homebrew but still doesn't work, does anyone know how to fix this? Thanks!

Answer 1

delete any old CMakeCache.txt in current project and dependencies and rebuild solves the problem.
