That's all fine and dandy (and you've written some nice prose about
it :), but I've just been reading man cmakecommands of Debian cmake
2.8.1-5(!) from top to bottom and bottom to top, and nowhere does it
mention _any_ underlying difference between macros and functions.

Not even I knew about this difference, despite having almost a month-full
of rather very internal CMake experience (Google searches in the couple
hundreds, vcproj2cmake adaptation of a _large_ project etc.).

Suggestion for the sake of world peace: I'll submit a patch for that man
page, ok? :)
