<p>Not the answer you'll probably want to hear, but:<o:p></o:p></p>
<p>- Use an up-to-date compiler<o:p></o:p></p>
<p>- Use package distributions like vcpkg or conda-forge that already brings all the dependencies "for free"<o:p></o:p></p>
<p>- It seems you mix builds of different compilers (VS vs mingw). That's a bit asking for troubles ;-)<o:p></o:p></p>
