ROOT C++ : RooUnfoldのMacにおけるcmakeを用いたコンパイル

ROOTおよびC++の超初心者です。

実現したいこと

MacでROOTのRooUnfoldをコンパイルし、使用したい。

背景 / 発生している問題・エラーメッセージ

(1) MacにROOTをインストール。ROOT自体は起動した。
(2) RooUnfoldを使用するためにhttps://gitlab.cern.ch/RooUnfold/RooUnfold からRooUnfold-master.zipをダウンロード・解凍し、同ページの "Building the Library"の記述通りに以下を実行：

bash
1cd RooUnfold-master
2mkdir build
3cd build
4cmake ..
5make -j4
6cd ..
7source build/setup.sh

(3) しかし、以下のようなエラーメッセージが出てきてコンパイルできない。

bash
1$ cd RooUnfold-master 
2$ mkdir build
3$ cd build 
4$ cmake ..
5CMake Deprecation Warning at CMakeLists.txt:10 (cmake_minimum_required):
6  Compatibility with CMake < 2.8.12 will be removed from a future version of
7  CMake.

9  Update the VERSION argument <min> value or use a ...<max> suffix to tell
10  CMake that the project does not need compatibility with older versions.

質問内容

以上のエラーを解消し、Macで正常にRooUnfoldを使用するにはどうすれば良いでしょうか？
特に

bash
1ld: library not found for -lgcov
2clang: error: linker command failed with exit code 1 (use -v to see invocation)

のようなlikerのエラーと

bash
1warning: 'SetRegParm' overrides a member function but is not marked 'override' [-Winconsistent-missing-override]

のようなoverridesのエラーを理解・解決したいと思っています。
ROOTやC++を使ったことがほとんどなく、初心者質問で大変恐縮ですが、よろしくお願いします。

自己解決

CMakeList.txtの問題のようでした。
https://gitlab.cern.ch/RooUnfold/RooUnfold/-/tree/CMakeLists-fixからダウンロードしたものは正常にbuildでき、使用できました。
両者の違いは理解できていませんが、少なくともMac OSユーザーは"master"(https://gitlab.cern.ch/RooUnfold/RooUnfold/-/tree/master)ではなく"CMakeLists-fix"をダウンロードした方がよさそうです。
