You need add msys2 path and also use msys2 tools from bash shell on octave.

#octave prompt
cd (build directory path) #build directory
system bash #goto bash

#bash prompt

export PATH=$PATH:/c/msys64/usr/bin # enable use tools on msys2.

There is no such system on *native* windows. Each application has its own 
installer.
The msys2 is an exception. That is a tool which provide many applications and 
libraries 
through pacman package manager.

However, octave-4.1.0+ is built with gcc-4.9.3 with win32 thread model 
while applications and libraries build with gcc-5.4.0 with posix tread model.
In principle, there is compatibility problem of shared libraries of C and C++ 
so that we cannot use libraries on msys2.

Yesterday I consulted pytave web site and cloned source code.

You have to build python2 and boost using gcc-4.9.3 embedded with octave-4.1.0+ 
on windows.

For, python2 there is a possibility to use windows binaries on python web site 
because it has a *static library* "libpython27.a" for mingw compiler 
while python binary seems to be build with Microsoft compiler.
To install python2 binary, go to the python web site and download python 2.7 
binaries for 64 bit.

For boost, there seems to be no other way build by yourself and seem to be 
different from 
build on unix.
