Google Test build failure Ubuntu 20.04 CMake 3.16.3 g++ 13.1

As cloned from branch master, the cmake step for Ubuntu/gcc fails while building Google Test. The error is a possibly uninitialised variable "dummy".

This appears to be the result of CMake trying to use an obsolete version of hunter. It is resolved by setting the huntergate URL in line 6 of CMakeLists.txt to the latest version, found at https://github.com/cpp-pm/hunter/releases (0.25.6 at time of writing).
