Installation of libwacom

Install libwacom by running the following commands: 

mkdir build &&
cd    build &&

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

To test the results, issue: ninja test. To run additional tests, install pytest-7.2.1, python-libevdev, and pyudev, then remove the "-Dtests=disabled" option from the meson line above.

Now, as the root user: 

ninja install

Command Explanations

--buildtype=release: Specify a buildtype suitable for stable releases of the package, as the default may produce unoptimized binaries.

-Dtests=disabled: This parameter disables some of the more advanced tests because they require pytest-7.2.1 and other two Python modules beyond the scope of BLFS to work properly.
