# Build dbus-proxy if D-Bus Gateway is enabled

# dbus-proxy is a completely separate cmake project. In order to reduce the
# risk of unwanted interaction between the SoftwareContainer and dbus-proxy
# cmake setup, we add dbus-proxy using the ExternalProject module to isolate it.
#
# It does require some workarounds. When using ExternalProject, by default,
# the dbus-proxy would install when building (and not when installing) SC,
# and thus require permissions that are unusual when just building. For this
# reason, we install dbus-proxy locally in the build tree and add an install
# target to install it when SC is installed.
