allow local install

[mahairod]

This change allows local installation of a lib (into $DESTDIR)

No, I don't think it's going to work because according to the RPM packaging guide DESTDIR is supposed to be a build-specific destination directory, it's not supposed to have any effect on the actual contents of the rpm (and doesn't even have to exist on the system where rpm is being installed)

RPM packaging guide

I don't even mind RPM here. I just launch local make install. So suggested change allows local installation only.
Ah. Ok, I see it. Probably should shange to smth like TARGETDIR or whatever.
But how do you suppose to make custom install then? I can't see good solution right now.

The need for this appeared becasue I don't want (or can't) install into the root, but msg tool requires pkgconfig else I have to manually change all paths in the makefile. That's annoying really.

But how do you suppose to make custom install then?

Presumably by using empty DESTDIR -> targets local fs root, so something like: make DESTDIR= LIBDIR=/custom/path INCDIR=/somewhere/else build install

At quick glance: LIBDIR bits are already in there and used from rpm spec file, but possibility to override include file target dir would need to be added

Ok, so now one could call smth like
make LOCDST=$HOME/.local install-dev
