[cmake-developers] Suggest if function has lte gte operators

[Harry Mallon]

That is completely fair. Perhaps a bit of Friday brain from me. It still could reduce complexity if you are trying to do something more complicated.

In my opinion A is easier to read than B.

A: if ( $1 STRGREATER_EQ $2 AND $3 STRLESS $4 AND $5 STRLESS_EQ $6 )
B: if ( NOT $1 STRLESS $2 AND $3 STRLESS $4 AND NOT $5 STRGREATER $6)
