Summary0014836: find_package(Threads) fails on Mac OS X with Xcode 5.1.
DescriptionWhen CMake tries to find the threading libraries using find_package(Threads), it will fail on Mac OS X and Xcode 5.1.

It works fine with Xcode 5.0.
Steps To ReproduceTo reproduce, put the following in a basic CMakeLists.txt file:

--- Begin CMakeLists.txt ---
cmake_minimum_required(VERSION 2.8)
project(Test)
find_package(Threads REQUIRED)
--- End CMakeLists.txt ---

then run:

cmake -G "Xcode"

You get the following output:

-- The C compiler identification is Clang 5.1.0
-- The CXX compiler identification is Clang 5.1.0
-- Looking for include file pthread.h
CMake Error at /Applications/CMake 2.8-12.app/Contents/share/cmake-2.8/Modules/CMakeCInformation.cmake:37 (get_filename_component):
  get_filename_component called with incorrect number of arguments
Call Stack (most recent call first):
  CMakeLists.txt:2 (PROJECT)


CMake Error: Internal CMake error, TryCompile configure of cmake failed
-- Looking for include file pthread.h - not found
CMake Error at /Applications/CMake 2.8-12.app/Contents/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:108 (message):
  Could NOT find Threads (missing: Threads_FOUND)
Call Stack (most recent call first):
  /Applications/CMake 2.8-12.app/Contents/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:315 (_FPHSA_FAILURE_MESSAGE)
  /Applications/CMake 2.8-12.app/Contents/share/cmake-2.8/Modules/FindThreads.cmake:166 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)
  CMakeLists.txt:3 (find_package)


-- Configuring incomplete, errors occurred!
Additional InformationThis was working fine for us up until we upgraded to Xcode 5.1. Could it be just looking in the wrong place for pthread.h?

The strange thing is that if you just create a basic C file that includes <pthread.h>, it compiles fine in Xcode, so just sure what is going wrong here.

I suspect that this is a deeper problem. Please put this in a CMakeLists.txt, run it with cmake --debug-trycompile and attach the whole build folder here:

cmake_minimum_required(VERSION 2.8)
include (CheckIncludeFiles)
CHECK_INCLUDE_FILES("pthread.h" CMAKE_HAVE_PTHREAD_H)

Please find the output from the command attached to the bug. The CMake console output was:

[priestm@shfc02h60mwdhjq build]$ cmake -G "Xcode" --debug-trycompile ..

Are you using CMake 2.8.12.2? It had this fix for Xcode 5.1 since 2.8.12.1:

 CMakeDetermineCompilerId: Fix compiler line match for Xcode 5.1

Ahh, no, I was using 2.8.12. Just upgraded to latest version, and all appears well.

Cheers Brad. You can mark this bug as fixed.
