CMP0134

The default registry view is TARGET for the find_file(), find_path(), find_library(), and find_package() commands and BOTH for the find_program() command.

The default registry views in CMake 3.23 and below are selected using the following rules:

• if CMAKE_SIZEOF_VOID_P has value 8:

  • Use view 64 for all find_* commands except find_program() command.
  • Use view 64_32 for find_program() command.

• if CMAKE_SIZEOF_VOID_P has value 4 or is undefined:

  • Use view 32 for all find_* commands except find_program() command.
  • Use view 32_64 for find_program() command.

The OLD behavior for this policy is to use registry views 64 and 64_32 or 32_64 and 32 as default, depending of CMAKE_SIZEOF_VOID_P variable value. The NEW behavior for this policy is to use registry views TARGET and BOTH as default.

This policy was introduced in CMake version 3.24. Use the cmake_policy() command to set this policy to OLD or NEW explicitly. Unlike many policies, CMake version 3.26.0-rc3 does not warn when this policy is not set and simply uses OLD behavior.
