Adding option for static/shared CRT in MSVC & Windows fixes.

- MSVC users can now choose whether to use the static or shared
  C-Run Time (CRT) libraries explicitly.
- FindPackage() scripts now check that the lowercase libraries match
  the expected library names, as Windows uses CamelCase for some
  library names (other OSs don't).
