Summary:                    Xcode generator creating incorrect relative paths
Description: 
This came up in an Xcode project generated by CMake.
Basic problem looks like this:


eno:quack dave$
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool
-static -arch_only x86_64 -syslibroot
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk
-L/tmp/tst/build/quack/lib/Debug/quack -filelist
/tmp/tst/build/quack/runtime/Quack.build/Debug/quack_runtime.build/Objects-normal/x86_64/quack_runtime.LinkFileList
/tmp/tst/src/quack/../../build/quack/loon/Hoot.o -o
/tmp/tst/build/quack/lib/Debug/quack/libquack_runtime.a
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool:
can't open file: /tmp/tst/src/quack/../../build/quack/loon/Hoot.o (No such file
or directory)
eno:quack dave$
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool
-static -arch_only x86_64 -syslibroot
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk
-L/tmp/tst/build/quack/lib/Debug/quack -filelist
/tmp/tst/build/quack/runtime/Quack.build/Debug/quack_runtime.build/Objects-normal/x86_64/quack_runtime.LinkFileList
/tmp/tst/build/quack/loon/Hoot.o -o
/tmp/tst/build/quack/lib/Debug/quack/libquack_runtime.a
eno:quack dave$ 


The problem here is that /tmp/tst/src/quack/ is a symlink to /tmp/quack. 
Therefore, the path traversal of /tmp/tst/src/quack/../../build leads to /build,
which doesn't exist.

CMake generated this relative path as far as I can tell; “../..” doesn’t
appear anywhere in my CMakeLists or my cmake command  The Ninja generator works
fine.

Steps to Reproduce: 
Sorry I don’t have a small reproducer for you.
