 Then execute the configure script (you'll probably have to pass it the location of your dependency libraries, i.e.):
 ```
 ./configure --prefix=/where/to/install --with-libtoxcore-headers=/path/to/ProjectTox-Core/core --with-libtoxcore-libs=/path/to/ProjectTox-Core/build/core --with-libsodium-headers=/path/to/libsodium/include/ --with-libsodium-libs=/path/to/sodiumtest/lib/

+*Note:* If your default prefix is /usr/local and you happen to get an error that says "error while loading shared libraries: libtoxcore.so.0: cannot open shared object file: No such file or directory", then you can try running ```sudo ldconfig```. If that doesn't fix it, run:
+```
+sudo echo "/usr/local/lib/" >> /etc/ld.so.conf.d/locallib.conf
+sudo ldconfig
