[Openflipper] Disable plugin when building?

Hello,

When building OpenFlipper, how can I disable a plugin without renaming its directory?

I would expect some option passed to openflipper_plugin() in the plugin's CMakeLists.txt but could not find any documentation for that.

Looking at common.cmake it, say, DISABLE_PLUGIN_SimplePlugin is defined, then it will be disabled. But I cannot figure out where and how to define DISABLE_PLUGIN_SimplePlugin.

Sorry if this is too trivial. I do not know CMake well enough,

Best regards,

Waqar
