Hi Lucas,
thanks for your kind words.
(1) It was my mistake to put the libraries in same bin folder. If it is an issue for you, please remove the line set(LIBRARY_OUTPUT_PATH bin) from fuzzylite/CMakeLists.txt. I think that would do.
(2) The ui_* files should be located in folder qtfuzzylite. Make sure they are there, otherwise you may want to either check folder qtfuzzylite/ui to find them or make sure . is indeed in the INCLUDE_PATH (which it should given line include_directories(. ${CMAKE_SOURCE_DIR}/../fuzzylite) in qtfuzzylite/CMakeLists.txt).
Let me know if it helps.
Cheers.
