     Type:  defect          |     Status:  new
 Priority:  Normal          |  Milestone:
Component:  ports           |    Version:  2.3.1
 Keywords:  cmake           |       Port:  openjpeg
----------------------------+--------------------------------
 cmake is not finding the SDK when building openjpeg and  other ports that
 also use cmake

 My machine details:

 OSX  10.8.5,  Xcode 5.1.1 (5B1008),  cmake 3.0.0_2

 Xcode is installed from the App Store

 I also have a couple of Xcodes installed as /Xcode-3.x.x

 Here's the openjpeg error log:

 }}}

 The SDK is really at
 {{{
 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk
 }}}

 I tried setting SDKROOT in my shell environment to the correct location,
 but it did not work.
