Boost Python: "Mixing a dll boost library with a static runtime is a really bad idea..."

Mathhead200 (1016)
I am currently trying to create a python binding for a large C++ library. After some searching, I have decided to use boost/python.

I am running into a compiler error:
C:\Users\mathh\lib\boost_1_80_0\boost/config/auto_link.hpp(435): fatal error C1189: #error:  "Mixing a dll boost library with a static runtime is a really bad idea..."


After some searching, I saw someone used #define BOOST_PYTHON_STATIC_LIB to bypass this error, but when I do this, I get an error from the linker about failing to find python310.lib. I know where this file is, I think I just need to point to it from the linker options, but I don't know if using a static library is a good idea here. To be honest, I'm not sure what the differences are.

This is the first time I've used boost. It's the first time I've tried to create a python native binding. And I haven't messed with DLL files in quite awhile, and I was never very good at them to begin with.

I'm using the visual studio command line compiler "cl". I have all the include paths set up, and am trying to compile with the /LD option.

Any advice?
