undefined reference to *gtk something*

[GreedyTactician]

Can't build the project. Getting undefined reference.

Tried to fix it by half haphazardly throwing the following cmake code I found online but it didn't work:
FIND_PACKAGE ( PkgConfig REQUIRED )
PKG_CHECK_MODULES( GTK REQUIRED gtk+-3.0 )
INCLUDE_DIRECTORIES ( ${GTK_INCLUDE_DIRS} )
include_directories(${GTK3_INCLUDE_DIRS})
link_directories(${GTK3_LIBRARY_DIRS})
add_definitions(${GTK3_CFLAGS_OTHER})
...
target_link_libraries(app PUBLIC ${GTK3_LIBRARIES})

libgtk-3-dev is installed an up to date.

It might help to take a look the CMakeLists file in the test folder, as well as how other projects import NFDe. The information you have provided is too vague to give any definite answer.
