iOS cannot use openh264

[bukira]

Describe the bug

I have followed the docs on using openh263 but the docs are too old for the current os, they are 5 or more years old

https://trac.pjsip.org/repos/ticket/1947 https://github.com/cisco/openh264/releases/tag/v1.6.0

Add libopenh264.a and iOS-SDK's libstdc++.dylib to your application project in Xcode.

libstc++.dlib is no longer part of Xcode since Xcode 9

When I try to compile openh264 I get cannot find libstc++.dlib as its no longer there

I can do this make OS="ios" ARCH=arm64 install -stdlib=libc++

which seems to create the libraries, but when I try to use in pjsip

./configure-iphone --with-openh264=/usr/local/openh264/lib/

I just keep getting

Using OpenH264 prefix... /usr/local/openh264/lib/ checking OpenH264 usability... no

How do I support openh264 with current OS and Xcode 12

Steps to reproduce

followed the docs

PJSIP version

2.11

Context

when trying to configure with openh264

Log, call stack, etc

Using OpenH264 prefix... /usr/local/openh264/lib/
checking OpenH264 usability... no

This is helpful
