Cannot compile on Ubuntu 20.04 (Focal)

Hello,

I get this error when compiling the current master (be185b4) on Ubuntu 20.04:

%sudo make install

Am I missing something?

Because of the g_uri_split function, blockit requires at least glib 2.66 to be installed. Sadly, Ubuntu 20.04 repositories contain the 2.64.6 version. Ubuntu 20.10 and up seem to support the required version. I should probably replace the function with something more "older glib friedly", but I don't have much time right now, sorry. I don't use Ubuntu, but this question might be helpful: https://askubuntu.com/questions/265111/install-a-single-specific-package-from-future-distribution.
