use explicit file paths for CMake rather then globing, This is recommended by cmake devs.

globbing vs explicit is discussed here.
http://www.cmake.org/pipermail/cmake/2008-December/025694.html

Practical implications are:
- developers need to keep CMakeLists.txt files up to date.
- Users wont get strange linking errors if they build after a file is added, since CMake detects CMakeLists.txt is modified and automatically reconfigure.
