I'm trying to install an obscure scientific python package "pycotools3" on windows 10 in conda using pip (3.6.9 environment). I use it in my research software which runs fine on osx. It's an old package and no longer actively supported. I am required to test my software on Windows. Unfortunately pycotools3 won't install. I think because cmake can't find nmake.
CMake Error at CMakeLists.txt:23 (project):
Running
'nmake' '-?'
failed with:
The system cannot find the file specified
I've tried installing visual studio but this hasn't added nmake to any of the paths. What should i do to get nmake onto the machine and into the anaconda powershell path?

Reset to default 0PyCoTools3 ([PyPI]: pycotools3) is a pure Python package, and should install on any Python 3

Its one of the dependencies (and it has 113 of them) that has the problem, yielding the question ill formed. Also, it doesn't list the install command as it should ([SO]: How to create a Minimal, Reproducible Example (reprex (mcve)))
Python 3.6 seems like an odd Python 3 version to use, as its EoL is 3+ years ago
Hmm, as I noticed that [GitHub]: CiaranWelsh/pycotools3 doesn't have any dependency version requirements, I just attempted installing:

Since I used a VirtualEnv, I found [anaconda]: Installing pip packages that states:
However, you might need to use pip if a package or specific version is not available through conda channels.
So, there you go, problem solved (with no need of installing anything).
