Summary0014479: XCODE_DEPEND_HELPER.make doesn't work with iOS applications
DescriptionWhen working with static libraries in Xcode, there is a post-build step added by CMake to clean targets when a static lib is built. This is to work-around known limitations in Xcode.

The file that does the real work is XCODE_DEPEND_HELPER.make, and it includes lines of the format:

/bin/rm -f /<path-to-outdir>/bin/Debug/test.app/Contents/MacOS/test

This works fine for Mac OS apps, but doesn't work correctly for iOS apps. In that case, the actual binary file is not inside a "Contents/MacOS" folder, but instead just directly under the app directory, so the correct command should be:

/bin/rm -f /<path-to-outdir>/bin/Debug/test.app/test

Is there some setting that the iOS.cmake toolchain could set that would alter what is generated in this file? Or would CMake need to be extended to allow customisation of this file?
Steps To ReproduceCreate a CMake project that uses the ios-cmake toolchain (https://code.google.com/p/ios-cmake/ [^]) that contains a static lib and an iOS app that links against the static lib.

Build the app. Then update the code in the library.

When you build the app again, it won't relink the new library.
Additional InformationShould this defect actually be raised against the ios-cmake toolchain project instead?

XCODE_DEPEND_HELPER is a hack we had to use to work around the lack of link dependency checking in OTHER_LDFLAGS by Xcode. Fortunately Xcode 5 finally fixed that limiation.

CMake >= 2.8.12 with Xcode >= 5 does not use XCODE_DEPEND_HELPER.

For reference, the reason ios targets to not appear where CMake expects them is:

Thanks for the quick feedback Brad.

I've tested this with XCode 5 and CMake 2.8.12, and it now appears to work as expected. So you can resolve this as fixed for me.
