Subject: [PATCH] igvm_c: fix macOS compatibility for Makefile and
 post_process.sh

grep -oP uses Perl regex which is not supported by BSD grep on macOS.
Replace it with sed for version parsing.

sed -i without a suffix argument is GNU-specific and incompatible
with BSD.

use sed -i.bak which works on both GNU and BSD sed, and remove
the backup files afterwards.
