Great.

It is duplicated because the test memorizes the answers to make sure
the detection works for known cases.  The EXPECT_... definitions
encode the expected results for the HAVE_... definitions that are
set by the $<COMPILE_FEATURES:...> generator expressions.  This
way the test ensures that the detection works and its results
propagate all the way through genex evaluation correctly.

Please post the patch so far so we can look at it to see what may be
missing.  Once this part works then it may activate the real parts
of the CompileFeatures test and lead you to the portions of that test
that need to be filled in for the Intel compiler.

Thanks,
