Thanks,  I already have Find<name>.cmake files for all my projects 
(libraries I am implementing) and I can use them. The problem is that by 
using Find<name>.cmake files I am forced to compile and install each 
project (i.e. library) individually and in order so dependencies are 
satisfied. I want to create a single CMakeLists.txt file that would 
compile and install all the projects making sure dependencies are 
satisfied.  So far the <name>Config.cmake file seems the way to do this 
but if there is another better way please let me know.
