UPDATE
Aaaaaahm.. I just rewrote the namspaces (moved them into a utils-file) aaaaand now it builds and works ._.
So.. solved I guess?!
Though I'm still curios to whether I'm using cmake wrong or if it's fine the way I did it.
Would be nice if you'd let me know
Okay, I need help with cmake again *sigh* (I've wasted hours now and just can't get it to work the way I want)

Code:
# - Config file for the FooBar package
# It defines the following variables
# PICTUREIT_INCLUDE_DIRS - include directories for FooBar
# Compute paths
get_filename_component(PICTUREIT_CMAKE_DIR "${CMAKE_CURRENT_LIST_FILE}" PATH)
set(PICTUREIT_INCLUDE_DIRS "@CONF_INCLUDE_DIRS@")
This project builds just fine.
One
important note:
effects defines a namespace
PI_IMAGE which will be relevant later
Other Project using PictureIt (will be the kodi-addon as as soon as I get this thing to build)

I have no idea what so every why that namespace isn't accessible.
I know that normally you'd install a lib to the system (including the headers) but I don't want that as the kodi visualisation addon has to work on its.
That's why I'm doing the "list(APPEND INCLUDES ${PICTUREIT_INCLUDE_DIRS})"
I really hope you guys can help me out again
