Manually add include path for header files. CMakeLists.txt don't work but cmake works fine.
Hi,
After some fiddling with SDL2 I have finally been able to compile an example using cmake and make under mingw32 with msys.
Unfortunately CLion does not sees sdl2 header files that are being loaded correctly by the cmake itself.
In my github repository there is forked and little tweeked version of FindSDL2.cmake https://github.com/tarach/sdl2-cmake-scripts
It works fine when used with commands:
mkdir build
cd build
cmake .. -G"MSYS Makefiles"
make
For CMakeLists.txt like the fallowing:
project(simple-timeline-recorder)
cmake_minimum_required(VERSION 3.2)
set(CMAKE_CXX_
#include <iostream>
#include <SDL.h>
int main(int, char**)
{
if (SDL_Init(SDL_INIT_VIDEO) != 0)
{
std::cout << "SDL_Init Error: " << SDL_GetError() << std::endl;
return 1;
} else
{
std::cout << "OMG it finally works..." << std::endl;
}
SDL_Quit();
return 0;
}
But CLion fails to load header files from it.

Hi Sebastian,
Got it running with only one small change:
changed to:
I used the posted files as well as the FindSDL2.cmake from your Github account
To be sure I attached all the files I used, hope this helps!
Kind regards,
Viktor

And by the way: With using your approach (find_package instead of PkgConfig) I also solved my SDL Issues (https://devnet.jetbrains.com/thread/465255) ;-)
Yet there some tweaks to do (copying required dlls, getting rid of console window).
