cmake: Add missing keyword for TARGET form of add_custom_command.

The `TARGET` form of `add_custom_command` requires a keyword that defines the target build order. Newer versions of CMake (version 3.31 or later) warn if that keyword is missing. See: https://cmake.org/cmake/help/latest/policy/CMP0175.html#policy:CMP0175 Add the keyword `POST_BUILD` that prior versions of CMake assumed by default.
