I've done this before, I just can not recall what I did.
Running the cmake application (GUI, not command line). I need cmake to
include /opt/local/bin in the search path. In this instance, the make
file is running FindBISON, but there are other dependencies that I will
come to once I get past this one.
My search path for the shell does include /opt/local/bin, which is
where Mac Ports puts the version of Bison that I need.
Last time I did this, I also needed to adjust Xcode to use /opt as
well. My recollection on that was that I altered the package.
Any clues would be appreciated.
