Subject: [PATCH] cmake : use EXCLUDE_FROM_ALL to avoid patch-boringssl.cmake
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We have to separate the code path starting 3.28 because
`FetchContent_Populate` is now deprecated and will be completely removed
in a future version.
