This header basically just consists of C runtime #defines and functions, but with
an SDL_ prefix. Note this in the documentation so people don't waste their time
reading through things they already understand.
This is just stuff I noticed while working on the wikiheaders updates. A
thorough pass over all the docs would not be terrible, and maybe a simple
script to check for consistency (does everything have a `\since` on it? etc)
might be nice, too.
(if there's a newline in the output, it won't print the line in the Perl
script where the failure happened, so fix this in places where it's used
more like an assert than error reporting.)
- Also add watchos support to CMake (SDL does not support this platform yet)

If cmake is invoked with -DSDL_ALSA=OFF, the misleading warning
message "Unable to find the alsa development library" is printed.
It's misleading because no attempt was actually made to find the ALSA
development library. It's always printed by the CheckALSA macro if
SDL_ALSA is false.
This commit moves this warning message in the CheckALSA macro to being
printed if ALSA_FOUND is false. However, I don't see an explicit warning
message like this for the other macros that search for development
libraries, so I wonder if the message shouldn't just be removed
entirely. It seems redundant with the "Could NOT find ALSA ..." message
generated by cmake.
Before this commit:
$ cmake -B build -DSDL_ALSA=OFF
[...]
CMake Warning at cmake/sdlchecks.cmake:125 (message):

After this commit:
$ cmake -B build -DSDL_ALSA=OFF
[...]
-- Options:
-- SDL_ALSA (Wanted: OFF): OFF
[...]
$ cmake -B build -DSDL_ALSA=ON
[...]
-- Could NOT find ALSA (missing: ALSA_LIBRARY ALSA_INCLUDE_DIR)
CMake Warning at cmake/sdlchecks.cmake:123 (message):

All of the cmake invocations above were without the libasound2-dev
package installed.
