[CMake] CMake problem on Solaris with suncc

[Gerhard Gappmeier]

Hi all,

I try to build my program with cmake on Solaris using cc (suncc).
The problem is when activating "-xtarget=ultra -xarch=v9" I get linker errors 
"wrong ELF class: ELFCLASS64".
I created a simple hello world example to reproduce the problem.
It consists of a simple hello-library and a test program that links against 
it. Both should be compiled with the same settings, so I don't understand
why this linker error occurs.
Does cmake configure any 32bit settings that may conflict with xarch=v9 ?

Output:
