Why is my project still being linked using LINK instead of xilink?

I've just converted a project that used the Microsoft compiler to use the Intel one. I'm using Visual Studio 2013 and Intel C++ 15.

Now, looking at compiler output, I see the following:

1>icl: : warning #10210: problem with Microsoft compilation of 'Everything.cpp'
1>Everything.obj : warning LNK4229: invalid directive '/Intel(R) compiler non-linkable IL object file' encountered; ignored
1>LINK : fatal error LNK1561: entry point must be defined
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

So clearly we are still using Visual Studio's linker and this is why the build fails. So, can someone help me figure out how to get the project to use the Intel linker?

Thanks.
