I propose the addition of a BOOL type to the CMake language.
bool(variable [value])
would declare a variable of type BOOL, with an optional value

would be subject to boolean type constraint. A BOOL can take on the
following values. Any other assignment is an error.
"TRUE" class - TRUE, 1, Y, Yes, YES, y, yes, ON
"FALSE" class - FALSE, 0, N, n, No, NO, OFF, <empty>
Attached is a patch which removes "Y" and "N" from the recognized
values for true/false.
This patch may break stuff. I don't know if there are many people
who rely on "N" and "Y".
I am sure it will break something.... I don't think we can change
it now.

I might kindly disagree. There are many instances where backward
compatibility was broken in order to clean things up and move on.
Vtk 4.x to 5.x was one of those. My code broke with the 5.x release
BUT it was for the better. And more importantly I was given plenty of
notice that it was coming. The jump from 2.4 to 2.6 seems like a good
time to make the break and clean things up. As long as there is a
comprehensive list of breakage I don't think people will have a real
problem with it.
