Christoph Haag 2855616e32 build/cmake: Fix udev related warning
CMake Warning (dev) at /usr/share/cmake-3.18/Modules/FindPackageHandleStandardArgs.cmake:273 (message):
  The package name passed to `find_package_handle_standard_args` (UDEV) does
  not match the name of the calling package (udev).  This can lead to
  problems in calling code that expects `find_package` result variables
  (e.g., `_FOUND`) to follow a certain pattern.
Call Stack (most recent call first):
  cmake/Findudev.cmake:64 (find_package_handle_standard_args)
  CMakeLists.txt:71 (find_package)
