When using the "linker" through CMAKE_CXX_LINK_EXECUTABLE you do not
need to add the --run-linker when compiling sources, which (i think)
is a bad idea.
If you have a setup and time, i'd appreciate if you could investigate
the crash of cmake upon the ABI tests (if they happen to you) since i
can't.
One more thing you might want to know about the cl6x:
if you happen to implement function "foo" in bar.cpp and the same
function is also implemented in library foobar.lib which you use for
linking, you would need to take care of the order of arguments to cl6x
while linking:
if bar.cpp.obj is before foobar.lib cl6x will use foo from bar.cpp.
you would have to do that manually, it's not possible to achieve this
with cmake from what i know.
