CMake Deprecation Warning at CMakeLists.txt:22 (CMAKE_MINIMUM_REQUIRED):
  Compatibility with CMake < 2.8.12 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.

CMake Warning (dev) at /builder/shared-workdir/build/sdk/staging_dir/host/share/cmake-3.25/Modules/FindPackageHandleStandardArgs.cmake:438 (message):
  The package name passed to `find_package_handle_standard_args` (WSLAY) does
  not match the name of the calling package (Wslay).  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/FindWslay.cmake:5 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)
  CMakeLists.txt:164 (FIND_PACKAGE)
This warning is for project developers.  Use -Wno-dev to suppress it.
