I would love to switch to MariaDB, but over the last year I've tried installing it twice on different versions of Mac OSX and failed. I don't use Homebrew because generally it causes more problems than installing from source. So, I followed the Generic Build instructions:

https://mariadb.com/kb/en/mariadb/generic-build-instructions/

And here were my results trying to install:

MariaDB 10.1.8
on Mac OSX 10.10.2
with Xcode 6.3.2

$ cmake --version
cmake version 3.4.0-rc3

CMake suite maintained and supported by Kitware (kitware.com/cmake).

$ cmake . -DBUILD_CONFIG=mysql_release

$ make --version
