Subject: Explicitly set CMake policy 0169 to silence warning
X-Git-Tag: 2.2.3~36
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8d10c309d7d468b9b2ecfd8d5f1b063d6396af17;p=thirdparty%2Fzlib-ng.git

Explicitly set CMake policy 0169 to silence warning

The recommended `FetchContent_MakeAvailable()` is introduced in CMake
3.14 which is greater than `cmake_minimum_required()`.

CMake policy will effects subdirectories.

The `cmake_minimum_required(VERSION)` command implicitly calls
`cmake_policy(VERSION)`.

Closes https://github.com/zlib-ng/zlib-ng/issues/1788
