I changed EXE to that CMAKE RUNTIME thing, thanks.

That NAME/COMMAND thing doesn't work for me at all.  Can't find the binary
without the runtime output path explicitly added.

This is what I tried:

In parent CMakeLists.txt

ENABLE_TESTING()

set (CMAKE_TEST_COMMAND ctest -V)

function (add_unit_test name)
   if(NOT TARGET ${name})
      add_custom_target (check COMMAND ${CMAKE_TEST_COMMAND})
   endif()
   add_executable(${name} ${ARGN})
   add_test(NAME ${name} COMMAND $<TARGET_FILE:${name}>)
   add_dependencies(check ${name})
endfunction()


in subdirectory CMakeLists.txt
add_unit_test(unit_string_numeric_utils units/unit_string_numeric_utils.cpp
string_numeric_utils.cpp)
