Now you don't need the latest Wayland installed to build with
newer protocols supported, as they'll build correctly; even if
your system can't use them, we can make intelligent decisions
at runtime about what's available on the current machine anyhow.
This also simplifies some logic and possible failure cases in
the configure and CMake scripts.
Fixes Bugzilla #4207.

The LT_LDFLAGS in Makefile.in contain the $(DESTDIR) in -rpath, which instructs libtool to take a wrong path into account for linking.
The issue arises, if DESTDIR is passed at build time and installation time.
-rpath only should use $(libdir) for both SDL 1.2 and SDL 2.x.

"if we're already using libtool, why aren't we using it ?"; they've been inspired by the fact, that at that mark, neither libSDL2_test.a nor libSDL2main.a were being built correctly (not sure if it's fully broken or just because I've tested the out-of-tree build)

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...
Since we are loading shared objects dynamically, build our own version of the
core protocol symbols, so that we in the future can include protocol
extensions.
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().
