p7zip-zstd

Build instructions:

• From p7zip_* folder:
• Optionally copy makefile.{OS_arch_compiler} over makefile.machine, e.g. building for macOS needs it. Standard makefile.machine is for Linux systems.
• Compile "everything":

make all4
sudo make install

Read makefile.common to see available make targets. More build instructions in p7zip_*/README.
