Subject: [PATCH 1/2] Building without tests-tools

Today, we can't build mixxx without links to gtest/gperftools/benchmark

This PR allows building only mixxx and mixxx-lib targets without
tests-tools.

Two common cmake-definitions are added :
* BUILD_TESTING
* BUILD_BENCH

And one compile definition for test.main.cpp :
* USE_BENCH

This is helpful for packaging (gentoo here).

The negative effect is sorting of tests source files as soon
as they are called by mixxx-benchmark target.
