Since cmake 3.19, the following warning is shown:

  Compatibility with CMake < 2.8.12 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell

I thought someone fixed this a few weeks ago. Are you using the latest HEAD?

Hi. I'm on the latest release - 1.10.0, but looking at master's CMakeLists.txt, the requirement for version 2.8 is still there:

1. https://github.com/google/googletest/blob/master/CMakeLists.txt#L4
2. https://github.com/google/googletest/blob/master/googlemock/CMakeLists.txt#L45
3. https://github.com/google/googletest/blob/master/googletest/CMakeLists.txt#L56

Hello,
#3094 is merged quite recently (Jan/2021)
and so I think using 1.10.0 which was released in 2019 can't resolve above warnings

Oh, thanks for pointing that out. I was under the impression that all of cmake 2.8.x is raising warnings, so I didn't try HEAD. Yes, HEAD doesn't raise those warnings. Apologies for the noise.
