Add google/or-tools

[pmlandwehr]

Google's OR-Tools are maintained by Google but I'm not sure how easily they play with conda, so we might want to add `em.

@pmlandwehr you can assign it to me.

@sodre Has there been any more progress on this? I was looking this issue earlier when a friend pointed me to this thread.

[sodre]

@jGaboardi, I haven't made any more progress on this since 2017. I was trying to cover all the architectures at that time and failed to complete the macOS and Windows builds.

If you are only interested in Linux, I think it is possible for us to rebase the current branch and only enable the build for Linux. Let me know if you're interested on that.

[jGaboardi]

@sodre thanks for the super quick reply! And yes, I am very interested. The current OS I need a conda build of ortools for is RHEL 6.10, so this would fit my needs perfectly. Much good karma to you if we can get it up on the conda-forge channel.

EDIT
I have just been informed by the main person in charge of approving software install requests that only conda-forge packages from the following two channels mirrored by the US Census Bureau (which is the environment I am working in for this specific project):

• http://mirror1.csvd.census.gov/python/conda-forge/linux-64

• http://mirror1.csvd.census.gov/python/conda-forge/noarch

Okay, I'll continue the work this weekend.

[jGaboardi]

@sodre Also, I am working in python 2.7 due to a legacy code base.

Although I have never built conda package for or done a conda-forge release, I am happy to help you with this in any way that I am able.

[jGaboardi]

@sodre I wondering if anything more has been done in regards to getting the Linux build up on conda-forge? Please don't think I am trying to be pushy, I am in a time-sensitive situation for a particular project that I need to either be able to ask the person in charge of software to do conda install -c conda-forge ortools (easy option) or go to a committee for approval of pip install ortools (difficult option) . If this is still a work-in-progress, is there any timeline when it would be available? Either way, I want to reiterate that I am not trying to be a demanding jerk and really appreciate the work you are doing. Regardless of whether the conda-forge build will be completed for me to use for this particular project, I do believe the community would greatly benefit from ortools being available through conda.

Just to comment, as the creator of or-tools, thanks and tell me if you need anything.

Left a comment in google/or-tools#92 (comment) about repackaging the official wheels instead of building from source. Perhaps it's a good first step before trying to compile from source. In any case, ortools supports make builds without Bazel, as far as I understand.
