That should work.  In CMakeFiles/target.dir/depend.make where target is 
the name of a library or executable in your project, you should see the 
source level depends that cmake computes for your project.  Perhaps the 
-I or include_directories are not set up so that cmake can find the 
header files, or they are being included in some way that is confusing 
cmake.  If you could create a small example that would help.
