a2jmidid uses the Meson build system.
To configure the project, Meson's universal options (e.g. prefix) can be used to prepare a build directory:
meson --prefix=/usr build
One additional - project specific - option enables for building without D-Bus support:
meson --prefix=/usr -Ddisable-dbus=true build
To build the application Ninja is required:
ninja -C build
Meson is able to install the project components to the system directories (when run as root), while honoring the DESTDIR environment variable:
DESTDIR="/some/other/location" meson install -C build
