[CMake] CMake 2.8.8 Upgrade problem with Xcode on OS X 10.8

[Sean McBride]

Hi all,

I believe I am seeing this too.  I have 3 versions of Xcode installed:

/Applications/Xcode4.3.3.app
/Applications/Xcode4.4.1.app
/Applications/Xcode4.5-DP4.app

I am careful to have no spaces or weird characters in those names.  I am careful to use 'sudo xcode-select -switch' to point to the one I want.  I always start with an empty bin directory.

But CMake 2.8.9 always fails like this:

---------------------
-- Check for working C compiler using: Xcode
-- Check for working C compiler using: Xcode -- broken
CMake Error at /Applications/CMake.app/Contents/share/cmake-2.8/Modules/CMakeTestCCompiler.cmake:52 (MESSAGE):
  The C compiler "/usr/bin/gcc" is not able to compile a simple test program.

  It fails with the following output:

   Change Dir: /Volumes/Leopard/Users/sean/kitware/VTK-analyze-bin/CMakeFiles/CMakeTmp

  

  Run Build Command:/Applications/CMake.app/Contents/bin/cmakexbuild -project
  CMAKE_TRY_COMPILE.xcode build -target cmTryCompileExec2711236228
  -buildstyle Development

  xcodebuild: error: option '-buildstyle' is no longer supported
---------------------

If I rename one of my Xcodes to just "Xcode.app" and 'sudo xcode-select -switch' to it, things work fine.

Can anyone repro that?

Thanks,

Sean
