These CMake cache scripts are my first pass at replicating Apple's packaging
logic from autoconf. They can be used on any Darwin machine to approximate an
Apple Clang build.
The included README file includes documentation and a sample CMake invocation.

+CMake Caches
+============
+
+This directory contains CMake cache scripts that pre-populate the CMakeCache in
+a build directory with commonly used settings.
+
+The first two cache files in the directory are used by Apple to build the clang
+distribution packaged with Xcode. You can use the caches with the following
+CMake invocation:
+
+cmake -G <build system>
+ -C <path to llvm>/tools/clang/cmake/caches/Apple-stage1.cmake
+ -DCMAKE_BUILD_TYPE=Release
+ [-DCMAKE_INSTALL_PREFIX=<install path>]
+ <path to llvm>
+
+Building the `bootstrap` target from this generation will build clang, and
+`bootstrap-install` will install it.
