Hi there,

You seem to be doing some things which are not recommended. You shouldn't be 
starting with finding qmake, and you shouldn't include() the config files 
directly. Using include() directly is likely to have unintended consequences. 
The appropriate way to write an umbrella infrastructure is something like what 
is in these files:

http://quickgit.kde.org/index.php?p=extra-cmake-modules.git&a=blob&f=find-
modules%2FFindQt5Transitional.cmake

http://quickgit.kde.org/index.php?p=extra-cmake-
modules.git&a=blob&f=modules%2FECMQt4To5Porting.cmake

Why do you duplicate the RCC macro?

I just created a project which calls find_package(Qt5Core) in two 
subdirectories and uses Qt5Core_INCLUDE_DIRS, and it works for me. Please file 
a bug with a minimal testcase, preferably using find_package instead of 
include() as you do.

Thanks,
