A C++ Project

You can follow these instructions to get a decent idea on OOP in C++.

CMake

Refer this project's CMakeLists.txt files to know more about CMake. Note that this project depends on the SFML library.

About C++ building - Compiler options

Language standard flags

-std=c++20

Disabling compiler extensions

-pedantic-errors

Warning and error levels

-Wall -Weffc++ -Wextra -Wconversion -Wsign-conversion -Werror

Optimization

• -O0 is the recommended optimization level for debug builds, as it disables optimization. This is the default setting.
• -O2 is the recommended optimization level for release builds, as it applies optimizations that should be beneficial for all programs.
• -O3 adds additional optimizations that may or may not perform better than -O2 depending on the specific program. Once your program is written, you can try compiling your release build with -O3 instead of -O2 and measure to see which is faster.

Build configurations

Add -g to the command line for debug builds and -O2 -DNDEBUG for release builds. Use the debug build options for now.
