Does it support MinGW?

[i-am-neet]

I tried to build this project w/ MinGW on Windows 10

But, it seems failed when linking library

How can I solve it?
Thanks

Thanks for reporting, I will have a look at it over the weekend.

The compiler error suggests a missing destructor that I added in #129. Probably more issues arise when the compiler proceeds but I don't have a working MinGW setup that I can test with.

In case you want to contribute it would be beneficial to have a CI build with MinGW.
