My recommendation is to always use the "MODULE" keyword in find_package() when 
a Find-module is used, and to always use the "NO_MODULE" or "CONFIG" keyword 
if no Find-module is used.
This makes it clear for everybody what is used for searching, and cmake can 
report on exactly that.

Beside that, I think the error message explains in detail what went wrong:

"CMake Warning at CMakeLists.txt:83 (find_package):
  By not providing "FindDBusMenuQt5.cmake" in CMAKE_MODULE_PATH this project
  has asked CMake to find a package configuration file provided by
  "DBusMenuQt5", but CMake did not find one.

  Could not find a package configuration file provided by "DBusMenuQt5" with
  any of the following names:

    DBusMenuQt5Config.cmake
    dbusmenuqt5-config.cmake"

If you have suggestions how to improve it, I'm happy to hear.
