# Makefile for librenderbench.so
#
# Prerequisites:
#
#   MuPDF development files:
#     Fedora:         sudo dnf install mupdf-devel
#     Ubuntu/Debian:  sudo apt install libmupdf-dev
#     macOS:          brew install mupdf
#
#   PDFium shared library + headers:
#     Pre-built binaries: https://github.com/nicehash/pdfium-binaries/releases
#       - Download for your platform
#       - Extract somewhere (e.g. /opt/pdfium)
#       - Set PDFIUM_DIR below or pass it:  make PDFIUM_DIR=/opt/pdfium
#
# Usage:
#   make                          # build with defaults
#   make PDFIUM_DIR=/opt/pdfium   # specify PDFium location
#   make clean

# directly into libmupdf.a — there is no separate libmupdf-third.a.

# Override MUPDF_LIBS if your distro differs, e.g.:
#   make MUPDF_LIBS="-lmupdf -lmupdf-third -lfreetype -lharfbuzz -ljpeg -lz -lm -lpthread"
