What's the layout of the installed LPG2 ?

I'm building on Ubuntu 18.04 64 bits with `g++-9` with a custom script that builds the `lpg2` binary, to be able to build/run I needed to make the changes shown bellow.

Now I can run `lpg2` but it doesn't find the template files and I need to put all files on the same folder (I'm not using any extra command line parameters, not even `-include-directory=semicolon-separated-strings`), it seems that it expect the template files to be in some specific places but I can't find where they are specified, when I build it using `lpg2/CMakeLists.txt` there is no install option like `make install`.

I'm following the https://github.com/A-LPG/LPG2/blob/main/lpg-generator-templates-2.1.00/docs/Getting%20Started%20with%20LPG.pdf .

It seems that the default installation directories are missing somehow.

Can anyone give some clues here ?
