On newer CMake's, the following errors are reported:
```
CMake Warning (dev) at .... /vcpkg/installed/x64-osx/share/c-ares/c-ares-config.cmake:32 (if):
if given arguments:
"ON"
An argument named "ON" appears in a conditional statement. Policy CMP0012
is not set: if() recognizes numbers and boolean constants. Run "cmake
--help-policy CMP0012" for policy details. Use the cmake_policy command to
set the policy and suppress this warning.
```
Which corresponds to the following configured code:
```
if(ON)
set(c-ares_STATIC_LIBRARY c-ares::cares_static)
endif()
```
