Clownacy ac465d29b4 Mean CMake dependency overhaul
I'm taking a page from Dolphin's book, and including copies of each
dependency's source code. This combines the ease of use of including
pre-built libraries instead of needing to navigate a package manager
 - as is (or was) the case for MSVC - with the portability of using
packages. Granted, this method's more of a jack of all trades,
master of none, since it's *less* user-friendly than prebuilt
packages (compilation times), and you don't get the per-distro
compatibility fixes you'd get from a package manager.

You can still use system libs if you want. In fact, it's still the
default behaviour: compiling the libs manually is just a fallback.
I'll add an option to force-enable this soon, however, since it's a
nicer way to produce static MSYS2 builds than the hackish nightmare
that I was using before. Not to mention, having my own copy of the
sources means I can provide my own fixes and tweaks your package
manager may not. For example, I can combine MSYS2's FreeType
subpixel rendering with vcpkg's fix for SDL2 exporting its symbols
in static builds.

Relative mode testing

See test program at the bottom of this file.

Initial tests:

  • When in relative mode, the mouse shouldn't be moveable outside of the window.
  • When the cursor is outside the window when relative mode is enabled, mouse clicks should not go to whatever app was under the cursor previously.
  • When alt/cmd-tabbing between a relative mode app and another app, clicks when in the relative mode app should also not go to whatever app was under the cursor previously.

Code

#include <SDL.h>

int PollEvents()
{
    SDL_Event event;
    while (SDL_PollEvent(&event))
    {
        switch (event.type)
        {
            case SDL_QUIT:
                return 1;
            default:
                break;
        }
    }

    return 0;
}

int main(int argc, char *argv[])
{
    SDL_Window *win;

    SDL_Init(SDL_INIT_VIDEO);

    win = SDL_CreateWindow("Test", SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED, 800, 600, 0);
    SDL_SetRelativeMouseMode(SDL_TRUE);

    while (1)
    {
        if (PollEvents())
            break;
    }

    SDL_DestroyWindow(win);

    SDL_Quit();

    return 0;
}
