qmake: how to supply multiple variables via command-line?

Question

qmake allows to supply a variables via a command-line interface like this:

qmake "CONFIG += release" "MY_VAR = hello"

So i can use $$MY_VAR inside a .pro file. But is it possible to suply more than one variable such way? I have tried

qmake "CONFIG += release" "MY_VAR = hello" "MY_ANOTHER_VAR = hi"

But it did not work (raises error). Any hints?

Answer 1

The question is misleading. You CAN supply any number of variables.

.pro file:

....
message($$VAR1)
message($$VAR2)

qmake run:

qmake ... "VAR1=VALUE1" "VAR2=VALUE2"

compiler output:
