[v2,01/10] config: change ABI versioning for global
Checks
Commit Message
From: Marcin Baran <marcinx.baran@intel.com>
The libraries should be maintained using global
ABI versioning. The changes includes adding global
ABI version support for both makefile and meson
build system. Experimental libraries should be
marked as 0.

I wonder if we should rename this to abi_version rather than major_version?

Don't think this block should be needed. Windows generally supports using
"/" as a separator, even if traditionally "\" was used.

We don't support make on windows, so no need for using findstr.
