That needs a bit of trickery:

function(add_test_executable name)
  add_executable(${name} EXCLUDE_FROM_ALL ${ARGN})
  if(NOT TARGET test-exes)
    add_custom_target(test-exes)
  endif()
  add_dependencies(test-exes ${name})
endfunction()

add_custom_target(check
  COMMAND ${CMAKE_CTEST_COMMAND}
  WORKING_DIRECTORY ${CMAKE_BINARY_DIR}
  COMMENT "Running ctest")
add_dependencies(check test-exes)


This way you can run "make check" to build all the test executables and to run ctest afterwards.
