[CMake] Call a macro through a variable. Possible or not?

[Dmitriy Ovdienko]

Hello Marcel,

Quote from http://cmake.org/cmake/help/syntax.html


CMake supports simple variables that can be either strings or lists of strings.
Variables are referenced using a ${VAR} syntax. Multiple arguments can be grouped
together into a list using the set command. All other commands expand the lists as
if they had been passed into the command with white-space separation. For example,

  set(Foo a b c)

will result in setting the variable Foo to a b c, and if Foo is passed into another command

  command(${Foo})
