Error 1181 while building from source

I am receiving the same error across different versions all the way back to 0.3.8 saying:

I already installed libzip earlier. I believe the problem was with the following line:

CONDA_PREFIX or CONDA_PREFIX_1 environment variables not found for including and linking to boost header files.

I was using a normal Command Prompt earlier. I tried using Anaconda Powershell Prompt and it worked like a charm.

I had a similar issue. Adding ‘CONDA_PREFIX’ to environment with value as the path to your anaconda install fixed it.
