Comment (by mojca@…):

 I don't remember why, that's been a while ago, but it's also true that
 when I wrote that I was working with version 2011 or 2012, so things might
 have changed in the meantime (and maybe some library dependencies were
 dropped).

 References to `libxml2` include
 {{{
 ./mac/ExternalPrograms/scripts/autopano-sift-C.sh:
 -DLIBXML2_INCLUDE_DIR="/usr/include/libxml2" \
 ./mac/ExternalPrograms/scripts/autopano-sift-C.sh:
 -DLIBXML2_LIBRARIES="/usr/lib/libxml2.dylib";
 ./mac/ExternalPrograms/scripts/panomatic-lib.sh:
 -DLIBXML2_INCLUDE_DIR="/usr/include/libxml2" \
 ./mac/ExternalPrograms/scripts/panomatic-lib.sh:
 -DLIBXML2_LIBRARIES="/usr/lib/libxml2.dylib" \
 ./mac/ExternalPrograms/scripts-legacy/autopano-sift-C.sh:
 -DLIBXML2_INCLUDE_DIR="/usr/include/libxml2" \
 ./mac/ExternalPrograms/scripts-legacy/autopano-sift-C.sh:
 -DLIBXML2_LIBRARIES="/usr/lib/libxml2.dylib";
 ./mac/ExternalPrograms/scripts-legacy/panomatic-lib.sh:
 -DLIBXML2_INCLUDE_DIR="/usr/include/libxml2" \
 }}}
 but I'm not sure if any of those are actually being used. Feel free to
 revert my change and close the ticket if that's what you consider is the
 right fix. I really don't remember why I did what I did.
