Or add ...

      cmake -DCMAKE_INSTALL_PREFIX:PATH=$prefix

which is preferred, as if you begin doing things like...

      export DYLD_LIBRARY_PATH=$prefix

Everything's rainbows + unicorns, till you try running a
task out of cron or at the system level...

Then you have to determine how you'll set this so all processes
pickup this path... and if this path ever changes... or requires
multiple values... you'll have to keep all this straight...

I've tried this... It becomes complex...

For me, better to just use the cmake facility for setting this
for each $prefix path that's used.
