# CMP0185

Added in version 4.0.

`FindRuby` no longer provides upper-case `RUBY_*` variables.

`FindRuby` in CMake 3.31 and below provided result variables named with an upper-case `RUBY_` prefix. CMake 3.18 renamed them with a `Ruby_` prefix to match the name of the package, but continued to provide the upper-case `RUBY_` variables for compatibility.

CMake 4.0 and above prefer to provide only `Ruby_` variables and no longer provide `RUBY_` variables. This policy provides compatibility with projects that have not been updated.

The `OLD` behavior for this policy is to provide both `Ruby_` and `RUBY_` variables. The `NEW` behavior for this policy is to provide only `Ruby_` variables and not `RUBY_` variables.

This policy was introduced in CMake version 4.0. It may be set by `cmake_policy()` or `cmake_minimum_required()`. If it is not set, CMake does not warn, and uses `OLD` behavior.

Note

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