Question

I am trying to use the macro() command for a context-insensitive string replacement, but this:

cmake_minimum_required(VERSION 2.8)

MACRO(TestMacro mystring)
  message(mystring)
endmacro()

TestMacro("hello world")

message("hello world")

outputs:

mystring
hello world

rather than

hello world
hello world

as I would expect. Can anyone see what I’m doing wrong?

Answer 1

Try dereferencing the macro parameter:

MACRO(TestMacro mystring)
  message(${mystring})
endmacro()
