Thanks for your help.

I just assumed /usr/local/lib was a standard place to look for libraries.

Anyways, when I install OpenJPEG,  include goes in /usr/local/include and
lib goes in /usr/local/lib

My configure command is:


$ ./configure --enable-libopenjpeg --extra-cflags="-I/usr/local/include"
--extra-ldflags="-L/usr/local/lib"

and the results is

ERROR: libopenjpeg not found
