For the resason explained on the text you didn't quote. The user would
need to be aware of the difference and do:

if( MSVC )
  target_link_libraries(myproject libclang)
else()
  target_link_libraries(myproject clang)
endif()

Of course this is not a reason that makes impossible to do what you
suggest. I picked a trade-off. If the consensus is that using different
names is the right thing, it's okay with me. However, I don't accept
reasonings of the type: "since I only work on Linux I don't care about
whatever problems Windows users may have." Please keep in mind that for
MSVC users cmake is the only way of building LLVM/Clang.
