Hi Olivier,
Have you tried passing the prefix to your preferred libjpeg to
configure? For example:
./configure --with-jpeg=/usr/local
It is probably best for `agar-config --cflags` not to output the "-I"
for libjpeg, because it is only used internally in gui/load_jpg.c,
and none of the Agar headers need to include <jpeglib.h>.
