--------------------------+-------------------------------
 Build of `py37-scikit-learn` fails on macOS 10.15 with Xcode 11.1. Here is
 the relevant part of the log:

 {{{
 :info:build test_openmp.c:1:10: fatal error: 'omp.h' file not found
 :info:build #include <omp.h>
 :info:build          ^~~~~~~
 :info:build 1 error generated.
 }}}

 The full log is attached. The dependency `libomp` is installed, and and
 the problematic header file is available in path
 `/opt/local/include/libomp/omp.h`. Is the flag
 `-I/opt/local/include/libomp` missing, maybe?
