#! Usage:
#! \code
#! SIMPLE_TEST_WITH_DATA(<testname> <baseline_relative_location> [argument1 ...])
#! \endcode
#!
#! This macro add a test using the complete add_test signature specifying target using 
#! $<TARGET_FILE:...> generator expression. Optionnal test argument(s) can be passed
#! after specifying the <testname>.
#!
#! <baseline_relative_location> parameter should corresponds to a subfolder located in <CTKData_DIR>/Baseline
#!
#! Variables named KIT and CTKData_DIR are expected to be defined in the current scope.
#!
#! KIT variable usually matches the value of PROJECT_NAME.
#!
#! The macro also associates a label to the test based on the current value of KIT.
#!
#! The following parameter will be passed to the test:
#! <ul>
#!   <li>-D <CTKData_DIR>/Data</li>
#!   <li>-V <CTKData_DIR>/Baseline/<baseline_relative_location></li>
#!   <li>-T <PROJECT_BINARY_DIR>/Testing/Temporary</li>
#! </ul>
