This builds the plugin binary `tox.so` and installs it to `~/.weechat/plugins/`. If your WeeChat home is somewhere else, or you'd like to install the plugin in a different location (e.g. `/usr/local/lib/weechat/plugins`), replace the last command with a simple `make` and manually move `tox.so` to the correct location.
Now, depending on where you want to install the plugin binary:
- To install to `~/.weechat/plugins` (recommended): `cmake -DHOME_FOLDER_INSTALL=ON ..`
- To install to `/usr/local/lib/weechat/plugins`: `cmake ..`
- To install to `/usr/lib/weechat/plugins`: `cmake -DCMAKE_INSTALL_PREFIX=/usr ..`
- To install somewhere else: `cmake -DINSTALL_PATH=/some/path ..`
Next, install the plugin. You may need sudo for the last command, depending on install location.
