Using SDL2 with CMake

by

This blog post shows how you can do it: Using SDL2 with CMake

On Linux you can use a recent CMake (e.g. version 3.7) and using SDL2 works out of the box.

cmake_minimum_required(VERSION 3.7)
project(SDL2Test)

find_package(SDL2 REQUIRED)
include_directories(SDL2Test ${SDL2_INCLUDE_DIRS})

add_executable(SDL2Test Main.cpp)
target_link_libraries(SDL2Test ${SDL2_LIBRARIES})

Under Windows you can download the SDL2 development package, extract it somewhere and then create a sdl-config.cmake file in the extracted location with the following content:

set(SDL2_INCLUDE_DIRS "${CMAKE_CURRENT_LIST_DIR}/include")

# Support both 32 and 64 bit builds
if (${CMAKE_SIZEOF_VOID_P} MATCHES 8)
  set(SDL2_LIBRARIES "${CMAKE_CURRENT_LIST_DIR}/lib/x64/SDL2.lib;${CMAKE_CURRENT_LIST_DIR}/lib/x64/SDL2main.lib")
else ()
  set(SDL2_LIBRARIES "${CMAKE_CURRENT_LIST_DIR}/lib/x86/SDL2.lib;${CMAKE_CURRENT_LIST_DIR}/lib/x86/SDL2main.lib")
endif ()

string(STRIP "${SDL2_LIBRARIES}" SDL2_LIBRARIES)

When you now configure inside the CMake-GUI application there will be a SDL2_DIR variable. You have to point it to the SDL2 directory where you extracted the dev package and reconfigure then everything should work.

You can then include SDL2 headers by just writing #include "SDL.h".
