Comment 4 for bug 619045

It's easiest just to change default value of BUILD_UNIT_TESTS to false, and trunk wont build tests nor require unit test framework unless tests are requested. As this value is cached, changing default value affects only when running cmake to new build directory.

For other tests approach that is used in src/scripting/CMakeLists.txt is propably fine: test sub directory is only included if BUILD_UNIT_TESTS is true.
