Config Compile-Time Header++ (CTH++) is a tool for automatically generating C++ configuration headers at compile-time using JSON data and constexpr. It supports various build modes and offers flexible project configuration.
USAGE: cth++ [options]
OPTIONS:
Generic Options:
--help - Display available options (--help-hidden for more)
--help-list - Display list of available options (--help-list-hidden for more)
--version - Display the version of this program
cth++ options:
--cmake-target-current-build=<target> - Specify the current build target
--config=<path> - Path to the JSON configuration file
--dbg - Set build mode to debug
--development - Set build mode to development
--namespace=<name> - Set the global namespace name
--output=<path> - Output path
--prodaction - Set build mode to production
--rel - Set build mode to release
--std=<cxx standard> - Specify the C++ standard
--working=<path> - Set the project directory
