The following table contains a list of build options which are only useful in special circumstances, e.g. when
developing libprojectM, trying experimental features or building the library for a special use-case/environment.
| CMake option | Default | Required dependencies | Description |
|------------------------|---------|--------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `ENABLE_SDL_UI` | `ON` | `SDL2` | Builds the SDL-based test application. Only used for development testing, will not be installed. |
| `ENABLE_INSTALL` | `OFF` | Building as a CMake subproject | Enable projectM install targets when built as a subproject via `add_subdirectory()`. |
| `ENABLE_DEBUG_POSTFIX` | `ON` | | Adds `d` (by default) to the name of any binary file in debug builds. |
| `ENABLE_SYSTEM_GLM` | `OFF` | | Builds against a system-installed GLM library. |
| `ENABLE_CXX_INTERFACE` | `OFF` | | Exports symbols for the `ProjectM` and `PCM` C++ classes and installs the additional the headers. Using the C++ interface is not recommended and unsupported. |

| `ENABLE_VERBOSE_LOGGING` | `OFF` | | Enables code for `TRACE` and `DEBUG` log levels in release builds. By default, these will only be compiled for `Debug` builds. Enabling this will negatively affect performance, even if the actual log level is set to `INFORMATION` or higher. |
