Hallo,<br>
<br>
what is the difference between<br>
SET(variable )<br>
and<br>
UNSET(variable)</blockquote><div><br>Nothing. The unset command was added for completeness and so that there could be an additional option added to it to allow removal of cache variables. Also, it is often the case that someone reading CMake scripts for the first time might be confused over the meaning of set(foo) and think that it defines a variable setting it to empty when it actually undefines a variable. Hopefully over time, unset() will remove any confusion here. The command will be in the 2.6.3 release. Obviously please be careful using this command if compatibility with earlier versions of CMake is a concern.<br>
