I do not define DESTDIR anywhere.
message($$DESTDIR)
prints empty string.
Is there a way to know path to the target binary?

In message() need to use different notation for some reason:
message(DESTDIR: ($$DESTDIR))
I had such problem today. Solved only by looking at qmake .pro files examples in Qt mailing list. Another possible problem - clue variables:
# ${VAR} notation allows to append the contents of the variable to another value
# without separating the two with a space
isEmpty(DESTDIR): DESTDIR = $${IDE_BUILD_TREE}/lib/qtcreator/plugins
Without such notation I got empty DESTDIR variable. If DESTDIR is not set, I believe binary stays in build dir.

Different? You use the same $$DESTDIR as in the question. And the thing you posted here is not an answer at all. Please remove it. – Alexander Dyagilev Sep 13 '19 at 06:44

@AlexanderDyagilev Not same: `message(($$DESTDIR))` – Aleksey Kontsevich Sep 16 '19 at 19:20

These additional () means nothing. It just prints them. – Alexander Dyagilev Sep 20 '19 at 02:54

I do not remember exact problem - it did not work, think message() - qmake function, `($$DESTDIR)` - variable. Simple `$$DESTDIR` did not work. – Aleksey Kontsevich Sep 20 '19 at 17:08

I've just tried on a new project. My variant prints "", yours prints "()". It does not print the directory in both cases. – Alexander Dyagilev Sep 21 '19 at 04:16
