Disable assert

[debian]

Hello!
I use Qt-5.12.2, I can use qmake parameters release/debug for disable/enable debug build. Now I should disable assert, for this I should define NDEBUG.
I grep sources of Qt, but I don't found what qmake parametr release add NDEBUG macros, so my question - I should manually add NDEBUG or qmake make this at release build?
Thank you.

QMAKE_CXXFLAGS_RELEASE += -DNDEBUG

will apply the NDEBUG define to release builds only.
