3. get lzma.h and lzma dir from https://chromium.googlesource.com/chromium/deps/perl/+/master/c/include into /usr/local/include

   for f in lzma.h lzma/base.h lzma/bcj.h lzma/block.h lzma/check.h lzma/container.h lzma/delta.h lzma/filter.h lzma/hardware.h lzma/index.h lzma/index_hash.h lzma/lzma.h lzma/stream_flags.h lzma/version.h lzma/vli.h; do sudo curl https://chromium.googlesource.com/chromium/deps/perl/+/master/c/include/$f -o /usr/local/include/$f; done
