Tutorial: Improve Step 1
* Update minimum required version to 3.10 * Use VERSION argument to project command rather than separate variables * Replace `endif(USE_MYMATH)` with more modern `endif()` * Simplify the call to 'configure_file()' * Add comments to tutorial.cxx to use as anchors in documentation * Remove CMakeLists and TutorialConfig.h.in files that users should create. Consequently, remove Step1 from CMake tests.
