warnings in InstallRequiredSystemLibraries.cmake with ifort 18 on Linux

The issue I'm reporting here is very similar to #17550 (closed) and can be considered a follow-up ...

Similar to the Windows case reported earlier, I also see such warnings with ifort 18.0.1 on Linux (with a build of cmake's current git master):

With cmake 10.2 I also see the following ...

... but this one seems to be fixed by 7d1ed84c in 3.11.

As on Windows, I have only the Intel Fortran compiler installed, but not the Intel C++ compiler.
