This directory contains patch files to enable cotire for some popular open sources packages that
use CMake as a build system.
For example, to apply Cotire to LLVM 3.0, first copy `cotire.cmake` to a directory on the CMake
module search path (e.g., `llvm-3.0.src/cmake/modules`).
Then apply the corresponding patch:
$ cd /path/to/llvm-3.0.src
$ patch -p1 < /path/to/llvm-3.0.src.patch
Then proceed with an out-of-source CMake build:
$ mkdir build; cd build
$ cmake ..
-- The C compiler identification is GNU 4.2.1
-- The CXX compiler identification is Clang 3.1.0
...
$ make
