Building v2.0.322 for Ubuntu 22.04 (Jammy) results in error: "The source directory does not appear to contain CMakeLists.txt"

Hello LibGit2Sharp.NativeBinaries Team,

v2.0.322 native binaries for Ubuntu Jammy is not available on Ubuntu Lunchpad although present for newer Ubuntu versions so I am trying to build one from the source. My use case for the library is a Visual Studio Extension whose tests are run within a docker container. The .so and other libraries are needed within the container for the tests to run.

Now I downloaded the v2.0.322 archive, unpacked it and ran build.libgit2.sh. Note that instructions in the READ.ME advice to use dockerbuild.sh but I need use the former because I shall be building the library also in the docker during container creation.

After running build.libgit2.sh, I get the error. Please help.

CMake Warning:
Ignoring extra path from command line:

".."

The source directory "some/known/path" does not appear to contain CMakeLists.txt.
Specify --help for usage, or press the help button on the CMake GUI.**

v2.0.322 アーカイブ内の build.libgit2.sh から始め、その CMake の呼び出しを README の手順および dockerbuild.sh と比較します。Ubuntu 22.04 環境で失敗を再現してください。完了とは、スクリプトがソースディレクトリを正しく見つけ、CMakeLists.txt エラーなしで必要なネイティブライブラリをビルドできることを意味します。
