Azat Khuzhin 9f9989ea72 Properly detect changes in Rust code and recompile Rust libraries
Due to we need to substitude config for Rust builds (see #44762 for
details), the source dir is copied to the binary dir, but this is done
only once, so to detect changes in sources you need to run cmake,
without this patch.
