The library you are looking for can be installed like this:
sudo apt install libdbusmenu-qt-dev
sudo apt install libdbusmenu-qt5-dev (either one works)
However, You may not be able to use the
BitBudget binary once you have built it. I can build it successfully, but it won't run on my system, as it hasn't been updated for so long.
Assuming you downloaded the bitbudget tarball from Launchpad here to the
Downloads directory, do:
sudo apt install g++ libdbusmenu-qt-dev
tar xf bitbud*
Check that the binary works:
./BitBudget (for me it segfaults). If it fails for you too, then you can just delete the whole directory.
If it works, then install to the
sudo mkdir /opt/BitBudget
sudo cp BitBudget /opt/BitBudget
sudo cp bitbudget-daemon /opt/BitBudget/
sudo cp bitbudget.desktop /usr/share/applications/
sudo cp data/bitbudget.svg /usr/share/pixmaps/
This includes installing a desktop launcher to run the program so you should be able to run it just by clicking the icon, if it works on your system.
