[CMake] CheckLibraryExists behaviour with different compilers

[victor sv]

Thanks Nils for que quick response!

The error log is as follows (summarized):

Determining if the function METIS_SetDefaultOptions exists in the metis
failed with the following output:

After googling and reading this:

http://www.opal-rt.com/kb-article/undefined-reference-intel-fast-memset-build-error-related-rte-delay

I try to link against libirc.a and libimf.a and it works fine. I do other
test compiling a shared METIS library with Intel compilers and it works too.

There is something that I'm not well understanding ... If I build a static
library, even with Intel compilers, shouldn't this library contain all the
needed symbols?

Thanks again :)
Víctor
