## When -DFREETYPE_DIR is used in place of -DFREETYPE_LIBRARY above, it makes
## xpdf-tools compilation find the "libfreetype.so" (no versioning at end) in
## our gs ext.
## But -DZLIB_DIR and -DPNG_DIR are ignored because they go unrecognised, whereas
## -DZLIB_LIBRARY and -DPNG_LIBRARY are recognised by XpdfTools' CMake files.
## -DZLIB_LIBRARY and -DPNG_LIBRARY require full paths. So the first 2 lines of the
## following won't work:
#       -DZLIB_DIR=$prefix \
#       -DPNG_DIR=$prefix \
#       -DFREETYPE_DIR=$prefix \

## When specified in the following way, all 3 lines are recognised (freetype, zlib,
## png). The 3rd line can alternatively still use "-DFREETYPE_DIR=$prefix"
#       -DZLIB_LIBRARY=$prefix/lib/libz.so.1.2.7 \
#       -DPNG_LIBRARY=$prefix/lib/libpng15.so.15.30.0 \

# If compilation was successful, then we don't need cmake binaries anymore when
# packaging up xpdf-tools
