Summary:                    FindThreads doesn't clearly express it requires C
language enabled.
Description: 
The FindThread documentation doesn't express that is uses the try_run command
and requires that C support has been enabled, when pthread isn't in a system
include ( osx  xcode 5+, cross compilation ).

I think the documentation should be extended to state that FindThread requires a
project to have enabled the C language. It should also document how to properly
setup FindThread for cross compilation.

Ee should also consider falling back to the C++ compiler for the try_run if the
C compiler doesn't exist, and we don't have a toolchain.

Steps to Reproduce: 
run the minimal project at:
