Subject: [PATCH] contrib: librist: patch meson.build for libcjson
Debian is using cJSON from github.com/DaveGamble/cJSON, as well as
archlinux and homebrew, which is shipping a libcjson.pc file. Only
ubuntu is using a different version not including the .pc file.
Homebrew is also shipping a libcjson.pc file, and without this, it would
generate a pc file like that:
prefix=/foo/bar/vlc/contrib/x86_64-apple-darwin21
libdir=${prefix}/lib
includedir=${prefix}/include
Name: librist
Description: Reliable Internet Stream Transport (RIST)
Version: 0.2.4
Libs: -L${libdir} -lrist /usr/local/Cellar/cjson/1.7.15/lib/libcjson.1.7.15.dylib
Cflags: -I${includedir} -I/usr/local/Cellar/cjson/1.7.15/include
Which won't be valid, especially for a standalone build with the
macosx/build.sh script.
It was leading to undefined references to cJSON symbols when it's
installed from homebrew.
Backport from upstream 809390b3b75a259a704079d0fb4d8f1b5f7fa956.
