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`).
https://github.com/tschw/SDL/commits/patched
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...
-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

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

This patch is wrong: the structure in question has nothing to do with any
gcc version in use. I suggest reverting this adding a conigury check for
it, instead. Something like the following should do it: (configure needs
regenerating.)

When building sdl as shared lib, the version info is lacking in the final binary.
CMake gathers the right resource files into ${VERSION_SOURCES} but then doesn't do anything with them.

SDL2 installs it to /usr/x86_64-pc-linux-gnu/share/aclocal on cross hosts, attached patch makes use of CMAKE_INSTALL_FULL_DATAROOTDIR to support correctly installing to the arch independent location /usr/share/aclocal.

I recently looked into Unicode support in SDL2 and realized that
SDL_TEXTEDITING doesn't get triggered at all (Japanese IME).
According to others on IRC it works fine on Windows/Mac but not
for me on (arch)Linux.
When compiling SDL with autotools, IBus support is enabled by
default but not so with CMake.
I never used CMake before but got it working and also included
that pkg-config determines flags for dbus (FIXME in CMakeLists).
The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly
uninitialized data structure if loading the library first failed. A later try to
use EGL then skipped initialization and assumed it was previously successful
because the data structure now already existed. This led to at least one crash
in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was
dereferenced to make a call to eglBindAPI().
