Related PR #6382

1. Update the patch
2. Update the name of share/curl/curl-target-release.cmake to share/curl/CURLTargets-release.cmake
3. Case sensitive in Linux, the name(curl -> CURL) changed in curl by commit 6932849.
4. Fix same case value issue in cpr.

The new upgrade in Curl, it moved deprecated #define CURLE_SSL_CACERT CURLE_PEER_FAILED_VERIFICATION to ifndef block in commit 0fd4427f, we didn’t define CURL_NO_OLDIES, so the following code enabled:
#define CURLE_SSL_CACERT CURLE_PEER_FAILED_VERIFICATION

In cpr\error.cpp reference 2 cases that both have same case value, so it failed with ‘error C2196: case value '60' already used’.

case CURLE_PEER_FAILED_VERIFICATION:
return ErrorCode::SSL_REMOTE_CERTIFICATE_ERROR;
case CURLE_SSL_CACERT:
return ErrorCode::SSL_CACERT_ERROR;

So I removed one of them to fix it.

@ras0219-msft: A heads-up: CURL 7.64.1 breaks the darwinssl feature - and, hence, will break curl[ssl] on macOS.

This is fixed in the next version of CURL, which is scheduled for release 22nd of May 2019. (Note: This will require renaming the USE_DARWINSSL option to USE_SECTRANSP in ports/curl/portfile.cmake, with that new version of CURL.)

[past-due]

CURL 7.65 is now available.

Per the above, the USE_DARWINSSL option should be renamed to USE_SECTRANSP in ports/curl/portfile.cmake, for 7.65+.

Thanks a bunch for the heads-up, @past-due!
