Summary0015111: “File reference” warnings when building a CMake project with Xcode 6
DescriptionXcode 6.0 (Beta 4) newly warns the developer if a source file is member of multiple groups/targets.

CMake, in order to work properly, adds the main source file to several targets: my_target_name, ALL_BUILD, ZERO_CHECK. Hence, I get the following superfluous warning messages:

2014-08-26 13:47:48.406 xcodebuild[14099:1007] warning: The file reference for "CMakeLists.txt" is a member of multiple groups ("ALL_BUILD" and "ZERO_CHECK"); this indicates a malformed project. Only the membership in one of the groups will be preserved (but membership in targets will be unaffected). If you want a reference to the same file in more than one group, please add another reference to the same path.

2014-08-26 13:47:48.406 xcodebuild[14099:1007] warning: The file reference for "CMakeLists.txt" is a member of multiple groups ("ZERO_CHECK" and "example"); this indicates a malformed project. Only the membership in one of the groups will be preserved (but membership in targets will be unaffected). If you want a reference to the same file in more than one group, please add another reference to the same path.
Steps To ReproduceThe problem is reproducible with the minimal example attached to this bug report.

cd minimal_example_xcode6_problem
mkdir build && cd build
cmake -G Xcode ..
xcodebuild
Additional Information- Xcode 6.0 (6A267n), it's a beta version
- Warning does not show up for Xcode 5.1.1
- Warning does not show up if I remove the duplicated entries in the proejct.pbxproj file for the targets ALL_BUILD and ZERO_CHECK.
TagsNo tags attached.

Added another minimal example that shows a similar warning if the same file is added to two different targets: minimal_example_xcode6_problem_duplicated_files.zip.
