Building LibCurl with OpenSSL causes linker errors

Question

I have been trying to build LibCurl with SSL support for 2 days now, and I have followed about every guide on the internet, and google'd errors for hours. I finally got it to compile fine, but when I link to it, I am getting the linker errors listed below.

I am building with...

nmake -f Makefile.vc9 OPENSSL_PATH=c:\dev_mms\openSSL RTLIBCFG=static CFG=release-ssl

The following errors, when I google'd them said something about the OpenSSL libs not being linked to properly, but I looked at Makefile.vc9, and it definitely is including the proper libs for OpenSSL. Here are the linker errors (I removed about 50 of them just to shorten it), what can I do to resolve these?

You need to add

 libeay32.lib ssleay32.lib

To additional dependencies in the project configuration.
