When libcamera is built and tested before installing, it will
be unable to locate the path to proxy files, or previously
installed files in the system path may be incorrect to load.
Hence, when libcamera is not installed and running from a build
tree, identify the location of that tree by using libcameraPath(), and
from that point add relative path to the proxy file.
