    Introduce some selective environment-cleaning.
    
    Yesterday I learned that you can set CMAKE_GENERATOR in your
    environment to make cmake default to a generator other than ordinary
    makefiles. (I like Ninja.) So I added that to my default shell
    configuration – and overnight half a dozen of my bob builds broke,
    because they run cmake and expect to get the default makefile!
    
    I think the point of a build system is to be relatively standardised
    in this kind of thing, so let's just run all subprocesses with
    CMAKE_GENERATOR unset. No doubt there are other variables I could add
    to the list of things to clean, as and when I think of them.
