Makefile.linux

# Headless Linux build of prism.
#
# Requirements: g++ (C++17), libpng dev, zlib dev, libzstd runtime
# (a shim header in linux/shim covers the missing dev header; if the
# real libzstd-dev is installed you can drop -Ilinux/shim).
#
# Usage: make -f Makefile.linux -j$(nproc)

include Makefile.common

# Portable backend files shared with the Windows/Web builds.
