This project is called easycompile. It allows you to compile a given source archive, such as a file like "php-7.2.0.tar.xz". By default this will compile into the prefix /usr/. In order for this to work, the file at hand has to exist; in the case above, the file php-7.2.0.tar.xz has to exist locally. For more documentation, have a look at the link called Documentation on the bottom right side of this webpage.
