CMake complains

[abrock]

CMake (version 3.23.2) complains when I run cmake_release.sh on Debian testing:

Release build not found, making directory...
CMake Deprecation Warning at CMakeLists.txt:1 (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 /usr/share/cmake-3.23/Modules/FindPackageHandleStandardArgs.cmake:438 (message):
  The package name passed to `find_package_handle_standard_args` (GPHOTO2)
  does not match the name of the calling package (Gphoto2).  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/FindGphoto2.cmake:45 (find_package_handle_standard_args)
  CMakeLists.txt:20 (find_package)
This warning is for project developers.  Use -Wno-dev to suppress it.
