Building systemd

[David White <dr.white.nz@xxxxxxxxx>]

Hi,

  I have a stupid question about building systemd.

I need a particular package rebuilt to test some changes. I only need this one specific bin.

How can I link against the libsystemd-shared-256.so iin the default location?

/usr/lib/x86_64-linux-gnu/systemd/libsystemd-shared-256.so

When I build, it links against the lib in the build dir.

I'm running:

meson setup build

then ninja from the build dir
