Summary:                    LINK_LIBRARIES contains both libraries and flags, 
separate variables required
Description: 
For example, if I write my own link rule:
set(CMAKE_CXX_LINK_EXECUTABLE "echo \" <LINK_LIBRARIES> \" ")  LINK_LIBRARIES
will evaluate to : 
- flags (like: -rdynamic -Wl,-rpath,rpath1:rpath2 ...)
- static libraries (like: lib1.a -lthreads ...) 
- dynamic libraries (like: libdlib.so )

To support new gcc-compatible linking tools (for example  Synopsys VCS or
Cadence NCSIM ) flags and libs need to be separated: for example into some new
variables: LINK_LIBRARIES_FLAGS , LINK_LIBRARIES_STATIC, LINK_LIBRARIES_SHARED.

In that case user can simply define new linking rules, for example:
(CMAKE_CXX_LINK_EXECUTABLE "vcs -sysc -LDFLAGS \" <LINK_LIBRARIES_FLAGS> \"
<LINK_LIBRARIES_STATIC> <LINK_LIBRARIES_SHARED>  <OBJECTS>")
