Installation of Umockdev

Install Umockdev by running the following commands: 

mkdir build &&
cd    build &&

meson --prefix=/usr --buildtype=release .. &&
ninja

To test the results, issue: PATH=$PATH:/usr/sbin ninja test. The addition to PATH is needed if you use the starting scripts in The Bash Shell Startup Files, because some tests need to run udevadm. One test needs to be run in an X session.

Now, as the root user: 

ninja install

Command Explanations

-Dgtk_doc=true: Use this switch if you have GTK-Doc-1.33.2 installed and wish to rebuild and install the API documentation.
