[libcurl][openssh][x64-uwp] cannot set certification verify locations

Hi guys,

I'm installing libcurl with openssl support from vcpkg for UWP. But the
CURLOPT_CAINFO cannot be set correctly ("error setting certificate verify
location"). Just wondering if someone can help on this. I think this might
be a bug for UWP only, since the x64-windows build is working as expected.

Describe the bug

The x64-uwp build for curl, will fail with

curl_easy_setopt(curl, CURLOPT_CAINFO, cainfo.c_str()); curl_easy_perform(...);

Error message:

* error setting certificate verify locations:
  CAfile: C:\Users\okidogii\AppData\Local\Packages\df268f7d-b5b4-4991-9c68-8120a7b392bb_75cr2b68sm664\LocalState\cacert.pem
  CApath: none
* Marked for [closure]: Failed HTTPS connection

vcpkg install curl[http2,ssl,openssl,ssh] --triplet x64-uwp
vcpkg integrate install

cacert.pem is downloaded recently from curl website. And the x64-windows
version with openssl is working as expected.

Environment

   - OS: Windows (uwp)
   - Compiler: VS2019

To Reproduce
Steps to reproduce the behavior:

use [vcpkg](https://github.com/Microsoft/vcpkg) to build x64-uwp

1. vcpkg install curl[http2,ssl,openssl,ssh] --triplet x64-uwp
2. vcpkg integrate install

        FILE* stream;

        // change path to your app's LocalState folder.
        std::string path =
"C:\\Users\\okidogii\\AppData\\Local\\Packages\\df268f7d-b5b4-4991-9c68-8120a7b392bb_75cr2b68sm664\\LocalState\\stream.txt";
        if ((stream = freopen(path.c_str(), "w", stderr)) == NULL)
            exit(-1);

        curl_easy_setopt(curl, CURLOPT_VERBOSE, 1L);
        curl_easy_setopt(curl, CURLOPT_URL, "https://curl.haxx.se");

        // change path to your app's LocalState folder.
        std::string cainfo =
"C:\\Users\\okidogii\\AppData\\Local\\Packages\\df268f7d-b5b4-4991-9c68-8120a7b392bb_75cr2b68sm664\\LocalState\\cacert.pem";

        curl_easy_setopt(curl, CURLOPT_CAINFO, cainfo.c_str());
        res = curl_easy_perform(curl); /* always cleanup */
        curl_easy_cleanup(curl);

Expected behavior
curl can set the cainfo correctly.
