Clarification questions on BOOST_ROOT in ax_boost_base.m4 |

It looks like the Boost macro prioritizes /usr, /usr/local, /opt, /opt/local
ahead of $BOOST_ROOT. In other words, hard-coded directory paths take
precedence over an environment variable. I was surprised by this choice. Is it
intentional?
Similarly, the $BOOST_ROOT must have a "stage" in it, which means I can’t just
set $BOOST_ROOT to the location of my local installation. CMake takes this
environment variable as is.
I was able to get around both issues by setting --with-boost=$BOOST_ROOT when
running configure. I am just seeking clarification as to whether this is
expected behavior.
Thanks,
Chris Aycock
