Almost done! The OPJ_STATIC change that was introduced in OpenJPEG 2.1+
means FFmepg's configure script has to do some extra work. You'll see that
there are two check_lib calls for openjpeg-2.1. You'll need to mimic both
of those for v2.2. That is, the configure script diff should be:

...
+enabled libopenjpeg       && { { check_lib libopenjpeg
openjpeg-2.2/openjpeg.h opj_version -lopenjp2 -DOPJ_STATIC && add_cppflags
-DOPJ_STATIC; } ||
+                               check_lib libopenjpeg
openjpeg-2.2/openjpeg.h opj_version -lopenjp2 ||
+                               { check_lib libopenjpeg
openjpeg-2.1/openjpeg.h opj_version -lopenjp2 -DOPJ_STATIC && add_cppflags
-DOPJ_STATIC; } ||
                                check_lib libopenjpeg
openjpeg-2.1/openjpeg.h opj_version -lopenjp2 ||
...
