I'm having troubles with functions, the next example gives me an exception
function(foo x)
set(x 1)
raise_scope(${x})
endfunction()
foo(y)
message(STATUS "y=${y}")
terminate called after throwing an instance of 'std::logic_error'
what(): basic_string::_S_construct NULL not valid
Aborted
If I change ${x} to x the result y is not defined:
unction(foo x)
set(x 1)
raise_scope(x)
endfunction()
foo(y)
message(STATUS "y=${y}")
-- y=
-- Configuring done
-- Generating done
And the next example works:
function(foo z)
set(x 1)
raise_scope(x)
endfunction()
foo(f)
message(STATUS "x=${x}")
-- x=1
-- Configuring done
-- Generating done
If I understand your example, the raise_scope is the way to return
values from functions.
Thanks
