One of the goals of FindPythonLibs is to work when cross-compiling such
that one cannot run the interpreter natively.  That is one reason we
don't just ask the interpreter where to get the libraries.  There has
been some discussion about doing such lookups conditionally when we
can run the interpreter but also having a fallback.

If there is another way to get this information then please use it.
Otherwise I'd rather not guarantee that we provide the information.
Projects can always run the same execute_process call themselves.
