How to include ft2build.h in SDL2 CMake project - c++

Question

I want to compile a CMake project using SDL2 and SDL_ttf library.
I copied "SDL_ttf.c" & "SDL_ttf.h" into my src folder.
(EDIT: removed it, see comments)
I also added this to my CMakeLists.txt:
include_directories(${SDL2_TTF_INCLUDE_DIR})
freetype2 is also installed
but i get the error after calling make
src/SDL_ttf.c:28:10: fatal error: ft2build.h: No such file or directory
28 | #include <ft2build.h>
How do i properly install SDL_ttf to my system?
(https://github.com/libsdl-org/SDL_ttf/blob/main/CMakeLists.txt)
EDIT:
my CMakeLists.txt:
cmake_minimum_required(VERSION 3.7)
set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
add_definitions(-std=c++17)
set(CXX_FLAGS "-Wall")
set(CMAKE_CXX_FLAGS, "${CXX_FLAGS}")
project(SDL2Test)
set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_SOURCE_DIR}/cmake/")
find_package(SDL2 REQUIRED)
find_package(SDL2_ttf REQUIRED)
include_directories(${SDL2_INCLUDE_DIRS} src)
include_directories(${SDL2_TTF_INCLUDE_DIR})
add_executable(Zokoban src/main.cpp src/game.cpp src/controller.cpp src/renderer.cpp src/hero.cpp src/level.cpp)
string(STRIP ${SDL2_LIBRARIES} SDL2_LIBRARIES)
target_link_libraries(Zokoban ${SDL2_LIBRARIES} ${SDL2_TTF_INCLUDE_DIR})
EDIT2:
after sudo make install (SDL_ttf source) and removing the SDL-source files from my repo:

EDIT3
On another machine (debian11) i couldn't even compile the SDL_ttf - source

.. although ft2build.h is obviously installed:
ls /usr/include/freetype2/
freetype ft2build.h
EDIT4:
I downloaded from https://github.com/libsdl-org/SDL_ttf/releases "SDL2_ttf-2.20.0.tar.gz". And could configure, make and sudo make install SDL_ttf.
... but make my project is still not possible
