Why 'make test' and "./test/Test" - c++

Question

Now I'm setting up a c++ test environment with CMake. Actually I've realized what I want to do, but I'm confused by 2 different test output style.
In my example below, what 'make test' do actually? I think both 'make test' and './test/Test' output are same, but not exactly. 'make test' output is different from googletest output style. Although test results looks same, I couldn't be satisfied with these output.
Output Differences

You can modify the behaviour of ctest (which is what make test will ultimately execute) with environment variables.
For example:
CTEST_OUTPUT_ON_FAILURE=1 make test
This will print full output for test executables that had a failure.
