conjure asks for CPLEX_PATH even when cplex is added to PATH

[ndangtt]

conjure asks for CPLEX_PATH when calling conjure solve although I already have cplex in my PATH. Interestingly when I reverted back to a previous commit 6c29fbde9 (2019-11-19 14:31:13 +0000), CPLEX_PATH was no longer required. Is it an expected behaviour?

Error:
    Set environment variable CPLEX_PATH. Something like:
        CPLEX_PATH=/path/to/cplex/library conjure solve

Hmm, the old version working out of the box is slightly surprising to me. We were not passing --cplex-dll back then, and as far as I remember Minizinc would then only work if the dll was at a specific location. Which in turn means it wouldn't work on MacOS for example.

This is what I have in my .profile file, so I don't have to set the dll path environment variable every time. Can you do something like that too maybe?

export CPLEX_PATH=/Applications/CPLEX_Studio129/cplex/bin/x86-64_osx/libcplex1290.jnilib

Is this still an issue @ndangtt?
