[CMake] Combined Static Libraries

[Daniel J. Hilferty]

Would including the source increase compile time with CMake?   Since 
these libraries should only need to be built once, I would hate to 
recompile them every time I build the library.

For Windows builds - because these libraries are not standard, we do actually include the code for zlib, IJG (jpeg) and png with the distribution.   For Unix builds, we prefer to use the libraries already available on the user's system to prevent conflicts between library versions.
