building fail on github actions using cmake 3.30

Unknown CMake command "cmake_determine_compile_features". thats all, looks like cmake has changed a method name https://gitlab.kitware.com/cmake/cmake/-/merge_requests/9366

Thank you for reporting, this problem already fixed #851 but not release yet). Workaround use fixed source (fixed in d5bf7cf83d0c86c502b6b30d5f0c8dc3b3049a38).

@dr3mro does the latest master fix it?

[jlnr]

libpqxx 7.9.1 stopped compiling for me with the same error after both Homebrew and my Linux distro upgraded CMake to version 3.30. I can confirm that it is fixed on the latest master commit.

An official release that contains the fix would be greatly appreciated, because then package managers like Conan will pick it up.
