[CMAKE] Use new policies for CMP0005 and CMP0018 (#1481)

* [CMAKE] Fix for CMP0018
The new behaviour lets us explicitly disabling position independent code, avoiding the need to change undocumented variables

* LINK_DEPENDS is semicolon separated

* [CMAKE] Fix for CMP0005
it seems impossible to have cmake correct escape PROXY_CLSID_IS so move it to the header
