[Need Help] Some problems encountered when trying to package Wolfssl library
I'm trying to package [Wolfssl](https://github.com/wolfSSL/wolfssl) with Nimterop. I've read the documentation and learned the basics of using Nimterop, and I've created a [Repo](https://github.com/darkr4y/nimwolfssl) to try to make Wolfssl as a library for Nim.
In the process, I encountered the following errors:

```
# Saved to C:/Users/dev/nimcache/nimterop/toastCache/nimterop_2966161807.nim
C:\Users\dev\Desktop\NimPlayground\nimwolfssl\nimwolfssl.nim(63, 8) template/generic instantiation of `cImport` from here
C:\Users\dev\.nimble\pkgs\nimterop-0.6.13\nimterop\cimport.nim(704, 10) template/generic instantiation of `cImport` from here
C:\Users\dev\nimcache\nimterop\toastCache\nimterop_2966161807.nim(813, 43) Error: undeclared identifier: 'CRITICAL_SECTION'
```

By searching Wolfssl's C code, as you can see that a macro definition needs to be passed [here](https://github.com/wolfSSL/wolfssl/blob/2ebb47ec32a05014e47e0e88ea8da8b42b1cf32a/wolfssl/wolfcrypt/wc_port.h) (`wolfssl/wolfcrypt/wc_port.h line 320`).
I try to use `cDefine()` or `{.passC.}` to define macro `"USE_WINDOWS_API"` and still get this error, all our friendly Nim community, please help me to solve this problem, BTW Im testing this on Windows and Nim version is 1.4.2, Nimterop version is 0.6.13.
