Protect implicit link library extraction with policy CMP0054
CMakeParseImplicitLinkInfo tests arbitrary content with `if(MATCHES)`.
Set policy CMP0054 to ensure the line content is never interpreted as a
variable reference (which may also produce a CMP0054 warning).
While at it, also set policy CMP0053 to improve performance.
