# VCPKG based ports # base The subfolder `base` is a submodule from microsoft/vcpkg. It contains the base ports. # overlay The subfolder `overlay` contains specific patches required for certain ports which are not compatible enough. # overlay\_system\_qt The subfolder `overlay_system_qt` contains empty qt ports to allow installing qt via aqtinstall. This avoids having to compile the complete qt dependency which is a costly operation and takes a long time. It also contains patches for qt based ports to make sure they pick up qt installed this way.
