wip/or-tools: Google OR tools, need help with this error

[Mayuresh <mayuresh%acm.org@localhost>]

All dependencies of google or-tools package are now built and I am stuck
on the following error. (This is a part of my effort to eventually build
openlane2 ASIC implementation toolset on NetBSD.)

I have committed wip/or-tools if someone wishes to take a look. Please
provide pointers / suggestions on how to go about these. I am not very
familiar with CMakes.
