CMake Warning (dev) at
test/LuaJIT-debug-extensions-tests/CMakeLists.txt:30 (find_package):
Policy CMP0148 is not set: The FindPythonInterp and FindPythonLibs
modules
are removed. Run "cmake --help-policy CMP0148" for policy details. Use
the cmake_policy command to set the policy and suppress this warning.
This warning is for project developers. Use -Wno-dev to suppress it.
See https://cmake.org/cmake/help/latest/policy/CMP0148.html
Let's fix this warning.

there are three verbosity levels: quiet (0), default (1) and verbose (3).
I would left a comment that "2" is a verbose level.
Feel free to ignore.
