link with mkl ilp 64 intel c++ compiler

I am trying to compile my code with mkl. I was using intel c++ on linux compiler using -mkl=parallel option.

From the documentation, I understand this does not link with the ilp64 libraries but only with the lp64 library. I have to specify manually the libraries. Am I correct? I was thinking that using the parameter ilp64 when setting up the environnments variables using intel mkl batch file would tell the compiler to use the ilp64 version of the library. It looks it is not the case. In this case, I do not understand why there is a ilp64 parameter for the batch file. Am I missing something? This is very confusing and I lost several days to figure it out.

Thanks,

Marc
