It seems that we install pip twice: here and in test_osx.

I wonder whether all problems are resolved if we just add
pyenv-virtualenv into 'brew install' command in deps_osx?

9.4 is not OS X version, it is xcode version. Proposed name:

RelWithDebInfoWError build + test (OS X 10.13 High Sierra)

See the following links to match os_image values into OS X versions and
names:

https://docs.travis-ci.com/user/reference/osx/#macos-version
https://en.wikipedia.org/wiki/MacOS_version_history#toc

Now I see both versions are High Sierra. I don't see a reason to have
two target of the same Mac OS versions (even despite different xcode
versions).

Also consider: Travis-CI added Mojave builds:
https://blog.travis-ci.com/2019-02-12-xcode-10-2-beta-2-is-now-available

Also I still think fix cmakes for Mojave and tweak travis targets should
be in the separate commits.

Since we set 10.6 for some targets, the comment seems to be still
actual. I don't think we should remove it.

Can we use VERSION_LESS operation to simplify the code?

I think only the first 'message' directive is useful, others are
redundant.

Why the edge is between 10.12-10.13, while a problem we trying to solve
appears only on 10.14 (Mojave)?
