Can't include an installed library

edit

Hey, i started working with px4_msgs, i cloned and compiled the package properly but unfortunately i can't use the package when working on my own code with Clion: When i try to include the package It correctly link between the name and the external libraries, but can't actually include it in the code with the error that file not found.

Here is my CmakeLists file, If Someone faced this kind of issue and can help it will be awesome!!
