5 years ago You need to open directory called messenger in your terminal. You can change current directory to xyz by typing cd xyz or you can go up by typing cd ... To list all directory contents type ls -l. Probably all you need to do is type cd messenger. Another option is to find this directory in file manager and select Open in -> Terminal in the right-click menu.
Once you are in the right place in your terminal, you can paste commands from the step 2.
After doing the first part I went to start the build and this is what I receive
meson build
ERROR: Neither directory contains a build file meson.build.
