- Install wget explicitly to match openssl. - Install CMake explicitly. - Use newer miniconda link. - Reenable unittests. - gcc@9 + xcode@10 for osx due to missing <_stdio.h>. Other versions of gcc should also work. But as homebrew pour gcc@9 after update by default, so I just stick with latest version. - Disabled one external memory test for OSX. Not sure about the thread implementation in there and fixing external memory is beyond the scope of this PR. - Use Python3 with conda in jvm package.
