CMP0036 — CMake 3.27.7 Documentation

# CMP0036

The `build_name()` command should not be called.

This command was added in May 2001 to compute a name for the current operating system and compiler combination. The command has long been documented as discouraged and replaced by the `CMAKE_SYSTEM` and `CMAKE_<LANG>_COMPILER` variables.

CMake >= 3.0 prefer that this command never be called. The `OLD` behavior for this policy is to allow the command to be called. The `NEW` behavior for this policy is to issue a `FATAL_ERROR` when the command is called.

This policy was introduced in CMake version 3.0. CMake version 3.27.7 warns when the policy is not set and uses `OLD` behavior. Use the `cmake_policy()` command to set it to `OLD` or `NEW` explicitly.

Note

The `OLD` behavior of a policy is `deprecated by definition` and may be removed in a future version of CMake.
