use cmake from PyPI only when system executable is not available (#7514) 
Rather than pulling `cmake` from PyPI unconditionally, add it to build
dependencies only if the system `cmake` executable cannot be found.
This eliminates an unnecessary dependency on systems featuring CMake,
and ensures that whenever possible, a downstream patched CMake version
is used that is more compatible with the system in question.
