How to use SDL2_ttf in a CMake project?

I have my project in C using SDL2 and SDL2_ttf.

Here is my cmakelists file:

cmake_minimum_required(VERSION 3.5.0)
project(mygame VERSION 0.1.0 LANGUAGES C)

find_package(SDL2 REQUIRED)
find_package(SDL2_ttf REQUIRED)
include_directories(${SDL2_INCLUDE_DIRS} ${SDL2TTF_INCLUDE_DIR})

add_executable(mygame main.c
    classes/list/list.c
    classes/my_string/my_string.c
    classes/errors/errors.c
    classes/render/render.c
    classes/constants/constants.c
)
target_link_libraries(mygame PRIVATE ${SDL2_LIBRARIES} ${SDL2TTF_LIBRARY})

So after compilation I have SDL2/SDL_ttf.h not found error:

I've installed both SDL2 and ttf via brew and they are both found (a least cmake doesn't complain when i'm trying to find_package), but error is still there. Compiling project without SDL2_ttf is all good. I'm using vscode cmake extention on macos sonoma 14.2.1.

Calling find_package(SDL2_ttf) creates IMPORTED target SDL2_ttf::SDL2_ttf. Just link your target with it, and your target will obtain all needed include directories and libraries:

target_link_libraries(mygame PRIVATE SDL2_ttf::SDL2_ttf)
