CMP0064 — CMake 3.10.2 Documentation

# CMP0064

Recognize `TEST` as a operator for the `if()` command.

The `TEST` operator was added to the `if()` command to determine if a given test name was created by the `add_test()` command.

The `OLD` behavior for this policy is to ignore the `TEST` operator. The `NEW` behavior is to interpret the `TEST` operator.

This policy was introduced in CMake version 3.4. CMake version 3.10.2 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.
