That's good point.
Actually on lines 43-45 the variable EXIF_ROOT_DIR is set according to $ENV{EXIF_ROOT_DIR}
only if the first header-file of libexif is found in that folder. The same behaviour if
the variable EXIF_ROOT_DIR is set with -D option, so if you don't set the env one, but the
cmake one, it works.
Thanks.
