[vtk-developers] CMake command issue

[Ken Martin]

Hey Folk,

A quick question. I am adding macros/procedures to CMake because a few
people have asked for them and they are very easy to implement. My
question is on syntax. For example, consider the following simple
example:

MACRO(ASSERT value message)
  IF (NOT ${value})
    MESSAGE(${message})
  ENDIF (NOT ${value})
ENDMACRO(ASSERT)

My question is which of the following two invocations would be better?

ASSERT(WIN32 "we are not on windows")

or

INVOKE_MACRO(ASSERT WIN32 "we are not on windows")

The first is easier to read, looks and smells like a regular command.
The down side is that someone might confuse it for a regular command
(I guess C and C++ have the same issue)  The second format is a little
less clean, but it is clear that you are invoking a macro. Thoughts?

Thanks
Ken
