I have a problem with a self-written CMake macro, but I don't know
exactly what the problem is.
I have defined macro(SetIfElse var val def), which is supposed to assign
the contents of val to var, when val is defined; otherwise it should
assign the contents of def to var. This macro was inspired by the
macro(SET_IF_NOT_SET var val) from the CMake module CTest.cmake
When I feed the CMakeLists.txt file below to cmake, I would expect as
output: 'text=Hello World', but instead I get 'text=Sorry mate!'
Could you please explain what I'm doing wrong?
project(hallo)
cmake_minimum_required(VERSION 2.6)
# Set variable ${var} equal to ${val} if ${val} is defined; else to
${def}.
macro(SetIfElse var val def)
if(DEFINED "${val}")
set("${var}" "${val}")
else(DEFINED "${val}")
set("${var}" "${def}")
endif(DEFINED "${val}")
endmacro(SetIfElse)
set(hello "Hello World")
set(mate "Sorry mate!")
SetIfElse(text "${hello}" "${mate}")
message(STATUS "text=${text}")
Isn't this asking if the variable "Hello World" (which, btw, I believe
is not a valid variable name due to the space, although cmake is a touch
inconsistent in handling such) is defined?
I think what you want is:
SetIfElse(text hello "${mate}")
