Gcompris webp images : error decoding
Here are the commands I ran for building gcompris-qt myself :
sudo apt-get install -y libgconf-2-4 gconf2-common libqt5svg5-dev libqt5svg5 qtdeclarative5-dev qtmultimedia5-dev qml-module-qtquick-controls libqt5svg5-dev libqt5sensors5-dev qml-module-qtquick-particles2 qttools5-dev-tools qml-module-qtmultimedia libqt5multimedia5-plugins qtquickcontrols2-5-dev qml-module-qtquick-controls2
cmake ..
make .
./bin/gcompris-qt
The app works well for most games, but for example for the fishing game ("clickgame"), no images are loading.
I see the following message in the log :
qrc:/gcompris/src/activities/clickgame/Clickgame.qml:24:20: QML Image: Error decoding: qrc:/gcompris/src/activities/clickgame/resource/sea1.webp: Unsupported image format
It seems that probably some dependency is missing.
