How to link OpenGL related libraries on mac using cmake?

I am trying to complete a simple GLFW tutorial on mac using cmake, where I encounter a series of undefined symbol linking errors. I did my research regarding this issue and found no help. Below is my CMakeLists.txt.

cmake_minimum_required(VERSION 3.3)
project(GL_Template)
find_package(PkgConfig REQUIRED)
pkg_search_module(GLFW REQUIRED glfw3)
include_directories(${GLFW_INCLUDE_DIRS})

find_package(GLM REQUIRED)
find_package(GLEW REQUIRED STATIC)

include_directories(${GLM_INCLUDE_DIR})
include_directories(/usr/local/include)
include_directories(./include)
find_library(COCOA_LIBRARY Cocoa REQUIRED)
find_library(IOKIT_LIBRARY IOKit REQUIRED)
find_library(COREVID_LIBRARY CoreVideo REQUIRED)
message(${COCOA_LIBRARY})
message(${IOKIT_LIBRARY})
message(${COREVID_LIBRARY})


file(GLOB A_SOURCE ./src/*.cpp)

add_executable(Hello example/main.cpp ${A_SOURCE})
target_link_libraries(Hello ${GLEW_LIBRARY} ${GLFW3_LIBRARIES})
target_link_libraries(Hello ${COCOA_LIBRARY} ${COREVID_LIBRARY} ${IOKIT_LIBRARY})
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -framework Cocoa -framework OpenGL -framework IOKit")

Any help would be helpful. Below is the error message

I found the solution. Obviously the GLFW3_LIBRARY is not defined and the defined variable should be GLFW_LIBRARY.
