# If a port installs Qt version-specific binaries (e.g. "designer" which |
| 4 |
# existed as a Qt4 application and exists as a Qt5 application and will |
| 5 |
# probably be a Qt6 application) which should have a qtchooser-based |
| 6 |
# wrapper, the port should set `QT_BINARIES=yes`. |
| 7 |
# |
| 8 |
# When QT_BINARIES is set to yes, compatibility symlinks (in bin/, |
| 9 |
# designer -> qtchooser, so that qtchooser can run designer-qt5 or |
| 10 |
# whatever is the selected Qt version) are installed by the port. |
| 11 |
# |
| 12 |
# Versioned binaries in ports are conventionally installed in <ver>/bin/, |
| 13 |
# so qt5/bin/designer is the versioned form of "designer". |
