This is a collection of additional CMake modules. Most of them are from Ryan Pavlik (http://academic.cleardefinition.com).
These modules are probably best placed wholesale into a "cmake" subdirectory of your project source.
If you use Git, try installing git-subtree, so you can easily use this repository for subtree merges, updating simply.
For the initial checkout:
cd projectdir
git subtree add --squash --prefix=cmake git@github.com:bilke/cmake-modules.git master
For updates:
cd projectdir
git subtree pull --squash --prefix=cmake git@github.com:bilke/cmake-modules.git master
For pushing to upstream:
cd projectdir
git subtree push --prefix=cmake git@github.com:bilke/cmake-modules.git master
At the minimum, all you have to do is add a line like this near the top of your root CMakeLists.txt file (but not before your project() call):
list(APPEND CMAKE_MODULE_PATH "${CMAKE_SOURCE_DIR}/cmake")

Modules based on those included with CMake as well as modules added by me (Lars Bilke) are under the OSI-approved BSD license, which is included in each of those modules. A few other modules are modified from other sources - when in doubt, look at the .cmake.
If you find this file inside of another project, rather at the top-level directory, you're in a separate project that is making use of these modules. That separate project can (and probably does) have its own license specifics.
