New submission from Bruno Abreu Calfa <bacalfa at gmail.com>:

File msvcr140.dll does not exist after installing Microsoft Visual C++ 2015 Redistributable or Visual Studio 2015. It has been replaced with vcruntime140.dll. See discussion here: https://groups.google.com/a/continuum.io/forum/#!topic/anaconda/yLH46ilPQeo

In addition, I was only able to build an extension (https://github.com/mattjj/pyhsmm) after copying the vcruntime140.dll from the Python installation folder (Anaconda 3 5.0.1 64-bit, Python 3.6.3) to the libs folder. I also had to change file include/pyconfig.h by removing the definitions of hypot (https://github.com/python/cpython/pull/880).

In sum, I suggest replacing

return ['msvcr140']


return ['vcruntime140']
