Android emacs build does not find/accept external library webp

Android emacs build does not find/accept external library webp

[Johan Widén]

I am building Android emacs from the emacs repo. But I am unable to get configure to find or accept external library webp.
I have cloned the webp repo according to java/INSTALL. I then fetched Android.mk and src/Android.mk from nougat-release.
The only modification I have made to them is to change the source listings in src/Android.mk to agree with Android.bp in android13-release.

java/INSTALL shows a patch for a Android.mk (for an older arm architecture, not relevant to me), but I do not recognize
the patch source lines in my src/Android.mk.

The patch is for Android.mk, not src/Android.mk, so you need only apply
it to the former file.  Thanks.

OK, I will work on this.

P.S.  I see that somewhere through our conversation, the list was
excluded from the Cc list.  In the future, please use ``reply all'' in
your MUA, so as to keep the list copied.

FWIW, the Windows installer people went through a somewhat similar process
in the past year or two, and may have usable tooling in this area. I added
Corwin as one of those involved; apologies to the others whose contact info
I have forgotten.

Hope this helps,
