fails to build

[rickysarraf]

I'm trying to play/integrate it with KDE+Wayland. But I run into compile issues.

rrs@priyasi:~/.../build ((v0.0.5))$ cmake ..
CMake Warning (dev) at /usr/share/cmake-3.21/Modules/FindPackageHandleStandardArgs.cmake:438 (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/Modules/Findudev.cmake:63 (find_package_handle_standard_args)
  CMakeLists.txt:24 (find_package)
This warning is for project developers.  Use -Wno-dev to suppress it.
