CMake support for versions <3.10 is deprecated and to be removed soon. Configuring fftw3 with the current min version leads to lengthy CMake warnings which clog the configure log.

It's annoying that merely being compatible with old versions (not requiring them) leads to warnings. 3.10 is only 7 years old.

Alternative would be to change to a more explicit range of compatible versions: cmake_minimum_required (VERSION 3.0...4.0). This would have the benefit of also fixing #381 which means one can again build with CMake 4 (which currently doesn't work).
