Build Errors On Ubuntu - QT

[nmnir]

When running cmake I'm getting the error:
CMake Error at UI/CMakeLists.txt:378 (add_executable):
Target "obs" links to target "Qt5::GuiPrivate" but the target was not
found. Perhaps a find_package() call is missing for an IMPORTED target, or
an ALIAS target is missing?

Build output is attached.

You are missing "qtbase5-private-dev" package at least.
