Hi Damir, May be the issue has nothing to do with the way you build the exported <>Config.cmake files. Since may be some nasty detail slipped in, could you tell us if the project is public. It looks like this one: https://github.com/DamirPorobic/kImageAnnotator
may be you can push a branch that contains the exact thing that fails on your side and it may be easier to review the detail? on the master of this repo there does not seem to have any "example" dir. However you already have hand written header file: https://github.com/DamirPorobic/kImageAnnotator/blob/master/src/gui/KImageAnnotator.h which has the very same name as the "exported header you generate": generate_export_header(kImageAnnotator EXPORT_MACRO_NAME KIMAGEANNOTATOR_API EXPORT_FILE_NAME ${CMAKE_BINARY_DIR}/include/KImageAnnotator.h ) so may be KImageAnnotator::KImageAnnotator(QPixmap const&) is exposed by the hand-written file and not by the generated one so that your unit test links ok but your "example" does not ? Did you check the content of the generated header file?
