Hello, I try to create a Flatpak package for my application
Here is what I did so far
flatpak remote-add --user --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
flatpak install --user org.kde.Sdk
(I use 5.15-21.08)
mkdir app repo
Then, I create a manifest in org.flatpak.myqtapp.json with this content
{
"app-id": "org.flatpak.myQtApp",
"runtime": "org.kde.Platform",
"runtime-version": "5.15-21.08",
"sdk": "org.kde.Sdk",
"command": "myqtapp",
"finish-args": [
"--share=ipc",
"--socket=x11",
"--socket=wayland",
"--filesystem=host",
"--device=dri"
],
"modules": [
{
"name": "myApp",
"buildsystem": "cmake-ninja",
"config-opts": ["-DCMAKE_BUILD_TYPE=RelWithDebInfo"],
"sources": [
{
"type": "dir",
"path": "../"
}
]
}
]
}
then I try to create the Flatpak using
flatpak-builder --user --ccache --repo=repo --force-clean app org.flatpak.myqtapp.json
But I get a basic error:
Emptying app dir 'app'
Downloading sources
Starting build of org.flatpak.myqtapp
Cache miss, checking out last cache hit

Add the installation prefix of "Qt5WebEngineWidgets" to CMAKE_PREFIX_PATH
or set "Qt5WebEngineWidgets_DIR" to a directory containing one of the above
files. If "Qt5WebEngineWidgets" provides a separate development package or
SDK, be sure it has been installed.

Error: module myqtapp: Le processus fils s’est terminé avec le code 1
Note that cmake has no problem to find Qt5WebEngineWidgets when I cmake/compile myqtapp in the classical way (withtout Flatpak).
I use Ubuntu 22.04 and official Qt5 Ubuntu packages.
Do you know how to solve that?
