# Support for our semi-homegrown libs/xpdf library. This is derived
# from xpdf source code, but xpdf does not distribute it as a library.
# It is used by pdftex (and nothing else) to read PDF images.
# Other engines use the semi-homegrown pplib library (q.v.) for that.
# The well-known poppler library is also originally derived from xpdf
# source code, but has been greatly revised and extended. TL used to
# (sort of) support poppler as the system xpdf, but after the TL 2020
# release we dropped this, because we switched XeTeX to use pplib, and
# nothing else used poppler. (No engines ever used poppler to generate
# their PDF output).
#
# poppler is aggressively developed, with requirements for new compilers
# and language versions. That's fine for them, but since we don't need
# anything new, it has become too time-consuming and problematic to
# continue to support it in the TL sources, when we don't have any
# requirement for it.
# KPSE_XPDF_FLAGS
# ---------------
# Provide the configure option '--with-system-xpdf' (if in the TL tree).
#
# Set the make variables XPDF_INCLUDES and XPDF_LIBS to the CPPFLAGS and
# LIBS required for the `-lxpdf' library in libs/xpdf/ of the TL tree.
