+Subject: [PATCH] openjpeg: Fix build against openjpeg 2.2
+
+OpenJPEG 2.2 has some API changes and thus ships its headers in a new
+include path. Add a configure check (to both meson and autoconf) to
+detect the newer version of OpenJPEG and add conditional includes.
+
+Fix the autoconf test for OpenJPEG 2.1, which checked for HAVE_OPENJPEG,
+which was always set even for 2.0.
