 Tox-WeeChat requires [WeeChat][1] >= 1.0.1, [SQLite][5] >= 3.6.19 and the latest-ish [libtoxcore][6]. It also requires CMake to be built. Installation is fairly simple; after getting the source, compile and install using CMake:
 
     $ mkdir build && cd build
-    $ cmake -DHOME_FOLDER_INSTALL=ON ..
+    $ cmake -DPLUGIN_PATH=~/.weechat/plugins ..
     $ make install
 
-This installs the plugin binary `tox.so` to the recommended location `~/.weechat/plugins`. Without the home folder flag, the binary is placed in `/usr/local/lib/weechat/plugins`. Installing to a custom WeeChat folder or elsewhere is achieved by setting `INSTALL_PATH`.
