There are no question before build-time (via Configure) to install libraries into a lib64/ directory, and headers into an include64/ directory. Default dirs are always lib/ and include/.
There is a solution, but a dirty solution because it does not take into account how the configuration really happens. Its a script that changes some occurrences of lib/ into lib64/ and some occurrences of include/ into include64/. Those changes should be read carefully and be integrated in a more proper way.

Created attachment 51 [details] Script making scattered changes to get files installed at the desired place. To allow a silent installation, lines 586 to 596 have been removed. This is why the Configure takes the answer to the questions on stdin. It also includes choice bewteen gcc ang icc.
This report was assigned to the wrong category, therefore not seen... Now reassigned to the right responsible.
We can add this functionality to Configure, but it's quite a bit of work and not a priority so I'm marking this as a LATER.
Marking as closed wont fix because Configure is not longer supported and CMake provides all needed functionality.
