Yes, CXML is Compaq Extended Math Library. You will first want to identify which CXML routines were used and then see if MKL has equivalent routines. Then, read the MKL documentation to see how you should incorporate those in your application. Typically, you would add a USE statement rather than an INCLUDE, but there is not one simple answer to substituting.
Read the MKL documentation and if you have further questions, please ask in the
MKL user forum.
