CMake options

• -D CMAKE_BUILD_TYPE=Debug
  • Enables debug info and disables optimizations
• -D CMAKE_EXPORT_COMPILE_COMMANDS=ON

  • Creates compile_commands.json for clangd language server.

    For clangd to find the JSON, create a file named .clangd with this content

    CompileFlags:
    	CompilationDatabase: build
    

    and place it here:

    .
    ├── vcmi -> contains sources and is under git control
    ├── build -> contains build output, makefiles, object files,...
    └── .clangd
    

• -D ENABLE_CCACHE:BOOL=ON
  • Speeds up recompilation
• -G Ninja
  • Use Ninja build system instead of Make, which speeds up the build and doesn't require a -j flag
