QMake - How and where to add linker flag?

Question

I tried to add the following in the .pro file of our project:

win32 {
    ...
    QMAKE_LFLAGS_WINDOWS += -Wl,--large-address-aware

}

I get an error LINK : warning LNK4044: Nicht erkannte Option /Wl,--large-address-aware; wird ignoriert.

Translation: unrecognised option /Wl,--large-address-aware; gets ignored.

Before that I tried to find out where to add linker options but it seems to be just a normal variable to put in the .pro file. I also searched for a searchcode entry in which the option is part of the .pro file.

I added the options to increase memory limit for the 32 bit application according to this post...

I use the following Qt Kit:

How to apply the option functioning?

@eyllanesc Now i get two warnings for both options `LINK : warning LNK4044: unrecognised option /Wl; gets ignored. LINK : warning LNK4044: unrecognised option /-large-address-aware; gets ignored.` — goulashsoup, Aug 14 '17 at 19:03
@eyllanesc With `"-Wl --large-address-aware"` I have exatly the same error as in my last comment. I added my Qt Kit. — goulashsoup, Aug 14 '17 at 19:17
I just readed your unedited comment about just trying the first option with capital letters but still the same: `unrecognised option /WL ...` — goulashsoup, Aug 14 '17 at 19:33
@eyllanesc `WL`: No, thats why I added the info that I want to increase memory and that I just copied it because I couldn't find anything else... — goulashsoup, Aug 14 '17 at 19:40
I would recommend that you use visual studio and try to activate that flag, maybe that flag is not active in your version of visual. — eyllanesc, Aug 14 '17 at 19:44

The linker options in the .pro file are for MinGW but I am using msvc so...

I had to add the linker flags just like in the msdn documentation with a slash and the linker option in capital letters. So for LARGEADDRESSAWARE:

QMAKE_LFLAGS_WINDOWS += /LARGEADDRESSAWARE
