Use GTK in your CMakeLists.txt instead of GTK3:

cmake_minimum_required(VERSION 3.0.2)
project(gtktest)

find_package(PkgConfig REQUIRED)
pkg_check_modules(GTK REQUIRED gtk+-3.0)

include_directories(${GTK_INCLUDE_DIRS})
link_directories(${GTK_LIBRARY_DIRS})
add_definitions(${GTK_CFLAGS_OTHER})

add_executable(gtktest test.cpp)
target_link_libraries(gtktest ${GTK_LIBRARIES})
