use NAME and COMMAND tags in add_test function

If CMAKE_RUNTIME_OUTPUT_DIRECTORY variable is specified, the ctest can't find executables for tests.

When add_test is used without NAME and COMMAND options, ctest tries to run tests with exact commands specified in add_test function. If CMAKE_RUNTIME_OUTPUT_DIRECTORY is specified, cmake moves binaries to that folder, 'exact command' from add_test is relevant any more and ctest is unable to find the binaries and fails (see documentation of the add_test function at the bottom of the page). To fix this issue just use NAME and COMMAND options.

Steps to reproduce:

mkdir build
cd build
cmake -DCMAKE_RUNTIME_OUTPUT_DIRECTORY=bin ..
make
ctest --verbose

This variable is usually used in big projects which set many options manually, and they usually set CMAKE_RUNTIME_OUTPUT_DIRECTORY variable to make it easier to find all output binaries. Some package managers that use cmake as underlying build tool also specifies this variable (for example, conan).
