Originally part of AWEngine, AWE Console is simple utility designed to be used similar to GoldSrc in-game Console.
Run ctest in build directory.
Executable of tests have prefix t_ (test abc would be executable t_abc).
After creating new test, add it to tests/CMakeLists.txt as add_subdirectory(abc) (where abc is name of your test).
To setup tests in CLion IDE, create new Run Configuration with Name=CTest, Working Directory=$CMakeCurrentBuildDir$ and Executable pointing to your ctest executable.
On Linux it will be /bin/ctest, on Windows probably C:\CMake\bin\ctest.exe
