What do I have to add for the QT Websockets module in CMake?

[Amazonasmann]

In my current project, I only need the Qt Websocket module. What do I have to add to my CMake file to link it correctly?

TARGET_LINK_LIBRARIES(main Qt5::WebSockets)
qt5_use_modules(main WebSockets)

does not seem to work. Any suggestions?

Hi,

Do you have find_package(Qt5WebSockets REQUIRED) in your CMakeList.txt file ?

[Amazonasmann]

sorry for the late answer, yes i have this in my CMakeLists.txt. Without this line, the output is something like " cannot use Websockets because it was not found yet".

CMake Error at CMakeLists.txt:24 (find_package):
By not providing "FindQt5WebSockets.cmake" in CMAKE_MODULE_PATH this
project has asked CMake to find a package configuration file provided by
"Qt5WebSockets", but CMake did not find one.
Could not find a package configuration file provided by "Qt5WebSockets"
with any of the following names:
Qt5WebSocketsConfig.cmake
qt5websockets-config.cmake
Add the installation prefix of "Qt5WebSockets" to CMAKE_PREFIX_PATH or set
"Qt5WebSockets_DIR" to a directory containing one of the above files.  If
"Qt5WebSockets" provides a separate development package or SDK, be sure it
has been installed.

-- Configuring incomplete, errors occurred!

I tried multiple installations on this machine including the online installer from the website and via apt-get. Is there an

apt-get install libqt5websockets-dev

or something available?

What version of Qt are you using ? And how did you install it ?
