[CMake] If syntax

[Mika.Rajala at patria.fi]

Hi

if(expression)
 ...
endif(expression2)

Makes an error since the expressions didn't match

I think this is the case with "else" as well.

However, i'm uncertain how to write it when you use elseif, maybe it still 
needs to match with the expression in the IF thing


The reasoning behind this, AFAIK, is to provide checking for errors in 
your scripts.

Feel free to leave those out from else and endif if you trust yourself : )
