Browse Source 
To prevent surprises when a build doesn't in fact contain the required
functionality suggest that users force-enable required modules.

$ meson build -Dsystem=true
Explicitly enabling required functionality
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
By default each module of functionality of libvirtd is optionally enabled,
meaning it will be enabled if the build environment contains the required
dependencies.
To ensure that your build contains the required functionality it's recommended
to explicitly enable given modules, in which case the configure step will end
with an error if dependencies are not present. **Example:** to build the
libvirt project with support for the **qemu** driver use the following options:
::
$ meson build -Dsystem=true -Ddriver_qemu=enabled
Notes:
~~~~~~
By default when the ``meson`` is run from within a GIT checkout, it will turn
on -Werror for builds. This can be disabled with --werror=false, but this is
not recommended.
