Adding 3rd Party framework path in pro file

[caduel]

when you write
# include <FrameWorkName/SomeHeaderFile.h>
then SomeHeaderFile.h has to be in a directory called FrameWorkName, and INCLUDEPATH should include /path/to/framework/Headers/ and the header themselves should be in /path/to/framework/Headers/FrameWorkName/*.h

Yes, I understand this. But when I put the framework in /Library/Frameworks/FrameWorkName.framework directory, this above conditions specified by you are not met and still code compiles correctly and that is why I am trying to find out why is this not working when I set the framework path to be something other than /Library/Frameworks/FrameWorkName.framework

Any idea?
