Significantly enhance modules/CMakeLists.txt to automatically figure
out in what order to add non-core module projects to Zorba. This was
necessary to extend the functionality of the automatically-created
moduleConfig.cmake files used in inter-module dependencies. These
files can now reference a "use file" to enable information such as
include directories to be shared to dependent modules.
