I was thinking the SDK would show a list of available ports, much in the
way it shows a list of available tools now. You could then install the
ports of interest. They wouldn't be downloaded until install so there
would be virtually no impact on the size of the sdk download.

You explained that adding -s USE_SDL=2 would cause emcc to fetch and
build SDL2 and include it in the app. I was wondering how you could
fetch and build just SDL2. If the result is stored in the cache though,
there is probably not much need to download and build it separately.
I am generating MSVS projects with GYP that include configurations for
building for Win32, x64 and Emscripten platforms. (I have modified GYP
to understand the vs-tool properties; I need to write some tests before
Google will incorporate the changes.) The issue I have is that, due to a
fundamental limitation of GYP, I have to use the same list of libraries
for each configuration. Therefore it would really be helpful if
* emcc (emlink?) recognized the names of built-in libraries (e.g. -l
libGLESv2) and ignored them, instead of searching for a library with
that name. I have had to create empty libraries to avoid errors.
* libraries from ports were added via, e.g. -lSDL2 during the link
step rather than -s USE_SDL=2 during compile. This would also be
more in keeping with native tool chains. At present I am using a
pre-compiled libSDL2 from gsathya with -lSDL2 on the link step and
it is working fine.
