The second issue is caused by binreloc. That's a small shim that allows an app
to run from a different <prefix> that the one it was built for and it doesn't
work if everything isn't contained under <prefix>. That's why
-DENABLE_BINRELOC=OFF is a suitable workaround for
-DCMAKE_INSTALL_PREFIX=/opt/gnucash not being able to find the environment
files. Perhaps the right fix is to simply force it off if installing to /opt/*.
