CMake Error at src/decoration/CMakeLists.txt:11 (add_library):
  Target "qgnomeplatformdecoration" links to target
  "Qt5::WaylandClientPrivate" but the target was not found.  Perhaps a
  find_package() call is missing for an IMPORTED target, or an ALIAS target
  is missing?

Hi, I don't know much about Pop OS, but I guess it's Ubuntu based? Can you try to install qtwayland5-private-dev?
