Whitespace in include folders breaks build
When using windows and using a folder with whitespace in nimterop folder, the build fails.
Unfortunately, my windows home folder contained whitespace for unknown reasons, so choosenim also crashes during installation and I have no real workaround. 

I got following error messages when performing `nimble build` in a folder containing whitespace:
```

```
The include folder direction `-Ifolder with whitespace` didn't use any quotes, so the whitespace made gcc expect a filename.
After adding surrounding double quotes `-I"folder with whitespace"` the build finishes without errors on my windows machine.

I created a PR for this to fix:

https://github.com/nimterop/nimterop/pull/271

Build succeeds on windows. Tests still do not work yet when having whitespace, but have no issues when using a folder without whitespace. So there might still some work to do to make it run without errors on folders with whitesapces. But I didn't want to change too much.

P.S.:
Do I need to open an issue or would it have been sufficient to create a PR?
