Summary:                    Optional arguments for macros are ignored by if()
Description: 
The issue was reproduced also on CMake 3.0.2 on OS X Yosemite.

Documentation points to the following :
"In the first case you can use if(${ARGV1}), in the second case, you can use
foreach(loop_var ${ARGN}) but this will skip empty arguments. If you need to
include them, you can use:"
http://www.cmake.org/cmake/help/v3.0/command/macro.html

But if on any ARGVXXX is always false.

An simple example is attached.
