Fix failing test for CMake 4 (#169)

* Add CMake minimum version command matching minimum version of CMaize

* Remove old 'cpp/' test directory reference and use relative paths for test names

* Default to using VERBOSE log level in tests

* Fix line numbers referencing bare_bones_cmake from the docs

* Revert minimum version of bare_bones_cmake example back to 3.5 to match other examples
