[Lazarus] Get LCL revision or version via ifdef

[silvioprog]

Hi,

I'm trying:

...
uses
  LCLVersion,
{$IF (LCL_MAJOR = 0) AND (LCL_MINOR = 9) AND (LCL_RELEASE <= 30)}
  Classes,
{$ENDIF}
...

But:

"Error: Compile time expression: Wanted STRING but got BOOLEAN or
INTEGER at "LCL_MAJOR = 0"".

How to I get the LCL version? (or revision)

Thx.
