It adds the meson and ninja build dependencies (since meson depends on ninja probably only the meson dependency is needed); sets the configure.cmd to meson and the build.cmd to ninja; adds args to make the build happen in an out-of-source build dir; adjusts how DESTDIR is supplied; and fixes a dylib install_name that ninja apparently generates incorrectly. The port doesn't supply any configure args so I don't know if those need to be handled differently. The port fails to build universal, so something is missing there.
I did not mean there is nothing else to do, but it seems simpler as what
is needed for cmake. meson using ninja to build is the same as cmake
using make. Just that ninja is an extra dependency as it is not assumed
to be provided by the system.
What is needed to fix the install name sounds like a bug in ninja and is
probably better addressed there, as I assume it affects all ports using
ninja, not just those which use meson in the configure phase.
