Most ironically, although autoconf/automake-based builds install (pretty half-assed) CMake package configuration files, they're missing in installations resulting from CMake-based builds entirely.
A proper configuration file typically also loads target exports (implemented in patch 3572, also fixing this issue - see my comment on that issue for details).
I believe it would be best to let the dinosaurs go extinct and redirect all build efforts to the CMake end for two reasons:
1. It potentially provides the best user experience, but you'd have to give it some love and ship with less quirky buildfiles.
2. It would force distros to build SDL via CMake and thus would ensure target exports are actually available everywhere.
Various CMake patches I submitted today in summary (directly converted from the HG commits and `am`d onto a fork of a git mirror that happened to be on `tip`).

Fixing #2576#3572, #3613, and this fresh ticket, which is almost entirely advertisement ;).
These already do to make SDL much less of a quirky fella to have in your dependency tree...

- list(APPEND EXTRA_CFLAGS ${MIR_TOOLKIT_CFLAGS} ${EGL_CLFAGS} ${XKB_CLFLAGS})
+ list(APPEND EXTRA_CFLAGS ${MIR_TOOLKIT_CFLAGS} ${EGL_CFLAGS} ${XKB_CFLAGS})
CFLAGS is spelled wrong in two different ways for EGL and XKB
And while you are on it...
sdl needs mir >= 0.24 afaik - it fails on travis-ci (ubuntu 14.04 LTS with 0.18 installed and in other environments, too (e.g. https://github.com/urho3d/Urho3D/issues/1685)
To fix this one should add a min version check to pkg_check_modules like this
- pkg_check_modules(MIR_TOOLKIT mirclient mircommon)
+ pkg_check_modules(MIR_TOOLKIT mirclient>=0.24 mircommon)
-Enabling checking for GCC_ATOMICS also on clang by default. This way all Android ABIs build successfully
-Android cmake: Threading was not enabled correctly
-Android cmake: Timers and dynamic lib loading were not included in the sources

Hi, I think I found a bug when using SDL_WINDOW_ALLOW_HIGHDPI with SDL_RenderSetLogicalSize on iOS. I use SDL_RenderSetLogicalSize for all my stuff. I just tried turning on SDL_WINDOW_ALLOW_HIGHDPI on iOS and suddenly all my touch/mouse positions are really broken/far-off-the-mark.
I actually don't have a real retina device (still) so I'm seeing this using the iOS simulator with a 6plus template.
Attached is a simple test program that can reproduce the problem. It uses RenderSetLogicalSize and draws some moving happy faces (to show the boundaries/space of the LogicalSize and that it is working correctly for that part).
When you click/touch, it will draw one more happy face where your button point is.
If you comment out SDL_WINDOW_ALLOW_HIGHDPI, everything works as expected. But if you compile with it in, the mouse coordinates seem really far off the mark. (Face appears far up and to the left.)
Alex Szpakowski on the mailing list suggests the problem is
"I believe this is a bug in SDL_Render?s platform-agnostic mouse coordinate scaling code. It assumes the units of the mouse coordinates are always in pixels, which isn?t the case where high-DPI is involved (regardless of whether iOS is used) ? they?re actually in ?DPI independent? coordinates (which matches the window size, but not the renderer output size)."
Additionally, if this is correct, the Mac under Retina is also probably affected too and "as well as any other platform SDL adds high-dpi support for in the future".

In some environments, xrandr modes initialization can fail even though xrandr support is present and of a sufficient version.
(The one I encountered was an AWS instance running a virtual display)
The attached patch allows SDL to keep trying other methods if xrandr modes initialization fails (still subject to SDL_VIDEO_X11_REQUIRE_XRANDR).

The attached patch adds support for KMS/DRM context graphics.
It builds with no problem on X86_64 GNU/Linux systems, provided the needed libraries are present, and on ARM GNU/Linux systems that have KMS/DRM support and a GLES2 implementation.
Tested on Raspberry Pi: KMS/DRM is what the Raspberry Pi will use as default in the near future, once the propietary DispmanX API by Broadcom is overtaken by open graphics stack, it's possible to boot current Raspbian system in KMS mode by adding "dtoverlay=vc4-kms-v3d" to config.txt on Raspbian's boot partition.
X86 systems use KMS right away in every current GNU/Linux system.
Simple build instructions:
$./autogen.sh
$./configure --enable-video-kmsdrm
$make
Now the clipboard isn't lost if you destroy a specific SDL_Window, as it
works on other platforms. You will still lose the clipboard data on
SDL_Quit() or process termination, but that's X11 for you; run a
Clipboard Manager daemon.
Fixes Bugzilla #3222.
Fixes Bugzilla #3718.

I think I found a better fix.
The problem with https://hg.libsdl.org/SDL/rev/ebdc0738b1b5 is setting the styleMask to 0 clears the NSWindowStyleMaskFullScreen bit, which then confuses Cocoa later when you try to leave fullscreen. Instead I'm just clearing the NSWindowStyleMaskResizable bit, although SetWindowStyle(window, NSWindowStyleMaskFullScreen); seems to also work.

Unfortunately this commit seems to have broken exiting desktop-fullscreen.
- Launch testgl2.
- Press alt+enter to go fullscreen-desktop
- Press alt+enter again. The spinning cube will freeze, and the window stays fullscreen desktop.

SDL_GL_GetAttribute doesn't check if a video driver has been initialized and will access the SDL_VideoDevice pointer, which is NULL at that point.
I think all of the attributes require an initialized driver, so a simple NULL check should fix it. Patch is attached.
