Yes "we" were, but "we" haven't got around to it :-)

Actually you have

    libdir = $(prefix)/lib/$(PackageId)/$(CompilerId)

which is better, as the FHS forbids creativity in the names of the
immediate subdirectories of /usr/local.  But maybe this is something
other than libdir, for which the conventional default is

    libdir = $(prefix)/lib

You'll probably also want substitution of variables in these strings
before too long.
