[Cmake] Making the cmake FindXXX.cmake files more consistent

[Ian Scott]

I've put a (slightly better) copy of this file in the CMake repository in
the Modules directory under the tag "tidy_modules"

You can get the modified version by going into the directory Modules and
typing
cvs up -r tidy_modules

I suggest we play around with the tagged version of some of these files
until we are happy with them.
