[FFmpeg-devel] [PATCH] configure: fix detection of libopenjpeg

[Andreas Cadhalpun]

Use check_lib2 to test the header together with the function. This is
necessary, because '-DOPJ_STATIC' changes what the included header does.

Also add '-DOPJ_STATIC' to CFLAGS, so that it isn't necessary to
hardcode this in libavcodec/libopenjpeg{dec,enc}.c.

Finally, check for non-static libopenjpeg, too.
