Linking error with twitcurl.lib/obj

```
This is related to another similar issue already posted. If you read the other
post, the recommended repair was to build from a curl source, and create
libcurl_imp.lib. I did that and I also added all the twitcurl source files to
my project. However, I still receive the same error.

I am using Visual Studio 10 Professional. I really need help with this.
Thanks
