STEPS TO REPRODUCE
1. Install all prerequisites (Everything I installed is listed in here: https://github.com/Jonchun/macify-linux/blob/1286ed3dbf1b928634f221c7c29942a6353e9e75/macifylinux/modules/lattedock.py#L12)
2. git clone https://github.com/KDE/latte-dock.git
3. cd latte-dock
4. ./install.sh

If I tried git checkout v0.9.10, It gets further along in the build process % wise, but then fails out with the same error.

According to https://github.com/KDE/latte-dock/blob/6e09bb5/README.md, building latte-dock requires KF5Wayland >= 5.38.0. The above shows it at 5.44 and is the only suspicious looking package in the requirements compared to the error message. To be honest I'm not sure what the 4: means.
