ANSI Colors in Command Prompt

{fmt} has this nice feature allowing you to use colors [https://github.com/fmtlib/fmt] for your output via ANSI escape code [https://en.wikipedia.org/wiki/ANSI_escape_code]. Too bad when I tried to run it under Windows the first time all I saw was the escape code

Debugging DLL, CMake, and Visual Studio 2019

One of the reasons why you want to use Visual Studio is because it has nice debugging interface. Support has been around for a while and now it is much easier to construct a cross-platform project using CMake. But if your project is like mine where you build a DLL

Filesystem Case Sensitivity

There may be many reasons why you must have filesystem that is case sensitive. For example, you are trying to run ct-ng build command and it fails under Windows WSL.

Date/Time Manipulations

C++ provides std::chrono::system_clock::time_point that represents time, that works well with other classes such as durations (std::chrono::milliseconds, etc.). However, it isn't always sufficient for date time manipulations because of daylight savings and leap years. Since time_point represents time interval since the
