[cfe-commits] r135216 - /cfe/trunk/CMakeLists.txt

[Douglas Gregor]

New Revision: 135216

URL: http://llvm.org/viewvc/llvm-project?rev=135216&view=rev
Log:
Tweak the CMake build so that building a project just containing Clang
(and linking to an already-build LLVM) works with Xcode. The resulting
Xcode project for Clang is quite a bit smaller and builds/loads faster.
