Each component of an upstream program has to design itself to use either Qt5 or Qt6. When you are packaging it in Debian, you have to use whatever the upstream code is designed for. Many programs are in the process of switching their code base from Qt5 to Qt6, which appears to be the case here.
README.md indicates that the upstream code requires Qt6 >= 6.6.
You need to make sure you have all of the components listed in the main CMakeLists.txt available in your Build-Depends.

target_link_libraries(bitmask PRIVATE
# Remove: L../../lib
Qt::Core
Qt::Gui
Qt::Qml
Qt::Quick
Qt::QuickControls2
Qt::Svg
Qt::Widgets
${LIB_TO_INCLUDE}
pthread
)
Most of these look like they are included in qt6-base-dev.

A bunch of others are in qt6-declarative-dev.

However, both of these packages are currently version 6.4 in unstable. Version 6.6 is being worked on as we speak, but if upstream really does have a hard dependency on 6.6 it isn’t surprising that it doesn’t currently build.
