[CMake] cmp0026, file(GENERATE...), and configure_file

[David Cole]

Of the modules, many of the "non-Find*" modules are exactly that. Of
the list here:

http://www.cmake.org/cmake/help/v3.2/manual/cmake-modules.7.html

The ones that pop out to me as obvious "CMake language function
providers" are ExternalProject, GetPrerequisites, BundleUtilities,
ProcessorCount. Mostly they're obvious to me because I have history in
each of those files.

The general convention to follow is, public functions in a module
should begin with the module name, followed by an "_", followed by the
function name. -- i.e. ExternalProject_Add is the "Add" function in
the ExternalProject module.


HTH,
David C.
