This commit fixes the issue I opened here : emscripten-ports/SDL2_ttf#1

On Debian the SDL_ttf.h file is included this way : #include <SDL2/SDL_ttf.h>
With emscripten the include must be modified in : #include <SDL_ttf.h>

As I know, the common way to solve this problem is by adding -I/usr/include/SDL2 flag while compiling your project into native machine code, and adding nothing else for emscripten build. With this technique you should be able to use #include <SDL_ttf.h> for both native and emscripten build without modify your code base.

Btw, using pkg-config would be the conventional way for specifying compiler flags in different environment.

If I misunderstand anything please let me know :)

Hi,
You're right, sdl2-config --cflags is also working fine to get the include directories. My pull request was targeted to source code not using the aforementioned ways to determine includes path. As include/SDL2 directory was existing yet in the emscripten cache, I though it was more coherent to provide SDL_ttf.h from this directory too, like it's done in Debian.

Hi,
Do you plan to merge this pull request ? If you prefer not, no problem, you can close it (you have enough pull requests to care with !).
