[gtk-osx-users] CMake issue when building latest GTK+.

[Pascal <p p14 orange fr>]

Hello,

I'm using MacOS 10.11 with XCode 7.3.1.
I've got CMake issue when building latest GTK+:

cmd$ jhbuild bootstrap
<...>
loading initial cache file /usr/local/src-gtk-osx/cmake-3.2.1/Bootstrap.cmk/InitialCacheFlags.cmake
CMake Warning at Modules/Platform/Darwin-Initialize.cmake:128 (message):
  Ignoring CMAKE_OSX_SYSROOT value:

   /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk

  because the directory does not exist.
Call Stack (most recent call first):
  Modules/CMakeSystemSpecificInitialize.cmake:18 (include)
  CMakeLists.txt:16 (project)


CMake Error at Modules/Platform/Darwin.cmake:76 (message):
  CMAKE_OSX_DEPLOYMENT_TARGET is '10.7' but CMAKE_OSX_SYSROOT:

   ""

  is not set to a MacOSX SDK with a recognized version.  Either set
  CMAKE_OSX_SYSROOT to a valid SDK or set CMAKE_OSX_DEPLOYMENT_TARGET to
  empty.
Call Stack (most recent call first):
  Modules/CMakeSystemSpecificInformation.cmake:36 (include)

Error when bootstrapping CMake:

*** Error during phase configure of cmake: ########## Error running ./bootstrap 
--prefix=/usr/local/xnadalib-2016 *** [8/23]

  [1] Rerun phase configure
  [2] Ignore error and continue to build
  [3] Give up on module
  [4] Start shell
  [5] Reload configuration
  [6] Go to phase "wipe directory and start over"
  [7] Go to phase "clean"
  [8] Go to phase "distclean"
choice: 4
exit shell to continue with build

[JH] cmd$ env | grep -i cmake
PWD=/usr/local/src-gtk-osx/cmake-3.2.1
CMAKE_PREFIX_PATH=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr

The only relevant Internet pointer I've found is not exactly my case as CMAKE_OSX_DEPLOYMENT_TARGET is not 
defined.

Any idea?

Thanks, Pascal.
