How do I build Lifeograph 1.51 from source?

Hello, I want the latest version but I can't build that version from source.

I am using Linux Mint 19.1 and I don't have required libraries.

I downloaded the lifeograph-1.5.1.1.tar.bz2, extracted it and the versions I have of grypt and enchant seem to be outdated in this distro. My actions in the console should be something like:

"""
$ cd ~/Downloads/src/lifeograph

$ sudo apt install build-essential libenchant-dev libgtkmm-3.0-dev libgcrypt-dev meson

$ meson --buildtype=release --prefix=/usr builddir

I don't have libenchant-2 so I get stuck there.

Or maybe I could add the ppa? I don't know the name of the ppa, but when I try:
sudo add-apt-repository ppa:lifeograph
it doesn't work.
