Summary:                    Support alternative download URL in
ExternalProject_Add
Description: 
We use a script with a lot of ExternalProject_Add to generate our dependencies.
But some project moves their files to different destination after some time. For
example: openssl

It would be very helpful if ExternalProject_Add could support alternative
download URLs as a list. So cmake could try the next URL if a connection error
occurs.

ExternalProject_Add(dummy
	URL "${FIRST_URL}" "${SECOND_URL}" "${THIRD_URL}"
)


Additional Information: 
OpenSSL:

Current version:
ftp://ftp.openssl.org/source/

If a new version arrives the old one will be moved to:
ftp://ftp.openssl.org/source/old/
