biicode just released the client code of their C++ Dependency Manager into OpenSource.

From the Website:

biicode manages your project’s dependencies so you can use the libs you need (Curl, Catch, Fann, OpenSSL, OpenCV, POCO, Boost, Libuv, GTest ...) as you wish within your project. biicode uses CMake to configure and build your projects and it is compatible with many IDEs, version control systems and compilers.
