I can't get gtkmm to compile on Mac using CMake

I'm attempting to set up an environment in which I can use gtkmm for C++ development. My CMakeLists.txt file looks like this:

cmake_minimum_required(VERSION 3.0.2)
project(program)

find_package(PkgConfig)
pkg_check_modules(GTKMM gtkmm-3.0)

link_directories(${GTKMM_LIBRARY_DIRS})
include_directories(include ${GTKMM_INCLUDE_DIRS})

file(GLOB SOURCES "*.cpp")

add_executable(program ${SOURCES})

target_link_libraries(program ${GTKMM_LIBRARIES})

Yet when I try to include the line include <gtkmm.h> in main I am met with this error from CMake:

fatal error: 'gtkmm.h' file not found
#include <gtkmm.h>

I installed gtkmm with brew using the command brew install gtkmm and brew install gtkmm3 to insure versions were not the issue. What can I do to get this working?

Be sure to install pkg-config (using brew).

Here is a CMakeLists.txt file that will work:

cmake_minimum_required(VERSION 3.16)

project(program LANGUAGES CXX)

find_package(PkgConfig)
pkg_check_modules(GTKMM gtkmm-3.0)

add_executable(program)

target_compile_features(program PRIVATE cxx_std_17)

target_sources(program PRIVATE main.cpp)

target_include_directories(program PRIVATE ${GTKMM_INCLUDE_DIRS})

target_link_directories(program PRIVATE ${GTKMM_LIBRARY_DIRS})

target_link_libraries(program PRIVATE ${GTKMM_LIBRARIES})
