Are you sure? The same macro works fine in a CMakeLists.txt file. I also
tried
message(MESSAGE)
and
message(${MESSAGE})
neither of which works (the first prints MESSAGE).
The macro is also the same as what is in the example here (without the
"" around but that shouldn't make an impact):

Based on my current knowledge of cmake the macro is proper cmake syntax.
Cheers,
