Compiling libwebsocket with newest QT

It appears that libwebsocket is the only library that does not come with Qt, so I think I need to compile it and install it in my QT folder so I can use with other things.

I tried to compile libwebsocket and I got this error:

qwebsocket_p.h:65:10: fatal error: private/qobject_p.h: No such file or directory
 #include <private/qobject_p.h>

I believe this is because the QT in my system is old. I have a QT installation in my home folder. How should I pass it to websocket?

If it were with cmake I'd have an idea, but I've heard here https://stackoverflow.com/a/49108604/10116440 that you cannot pass qt folder to qmake. Is there a way to pass to make?

I also tried doing this in cmake:

find_package(Qt5WebSockets REQUIRED)
find_package(Qt5 COMPONENTS Core Qml Quick Svg)

this way I can do cmake -DQt5_DIR=/home/lz/Qt5.11.2 . to set the Qt5 variable for everything except Qt5WebSockets, but the project fails to include <QWebSocket> anyway. If someone knows how to solve this, it'd also be good

private/qobject_p.h: No such file or directory

That means that the directory containing qobject_p.h was not added to the Include paths list. Make sure that your .pro has QT += core-private string.

It should be enough to put the file named qt.confto the directory containing qmake.exe:

qt.conf

[Paths]
Prefix = <qt root>
