# Linux build for the mzip unit tests.
#
# mzip_unit_tests.cpp includes zstd via a vendored Windows path
# (zstd_release/zstd-v1.5.6-win64/include/zstd.h), and the PPMd backend lives in
# ppmd/*.c with no gate script that compiles it on Linux -- gate_all.sh and
# gate_ppmd.sh are .dll/.exe lines. This target supplies both so the suite can run
# where the loop runs. It changes no source.
#
#   make -f Makefile.linux test
#
# Needs: g++ (C++17), libzstd-dev, liblzma-dev, libbrotli-dev.
