[CMake] Handling library dependencies and minimizing duplicated include_directories

[Aaron_Wright at selinc.com]

I've always been a little confused by FIND_PACKAGE and those 
"*-config.cmake" files. So much so that I didn't use them in my build 
system at all. The main question I have is that I have several developers 
and numerous little and big libraries. Because the whole project is so big 
it would be prohibitive for them all to work from a master CMakeLists.txt 
file at the top. I want each developer to be able to go the folder of the 
library they want to work on today and start building there. I want all 
the libraries that library depends on to be built or rebuilt if anything 
has changed in addition to building the current library. 

I've been unable to find a simple solution to this problem using CMake, 
which makes me wonder if what I'm doing is off the wall, but it sounds so 
normal to me. I see these "*-config.cmake" files but it seems they are 
generated from a CMakelist.txt file, which wouldn't make any sense, 
because I'm not going to have a developer go to each dependant library and 
build it seperately so that the "*-config.cmake" can be generated so that 
he can have those variables back in the library he really wants to build.

What am I missing?

Thanks a lot for your help Mike!
