Something like this is probably better (crudely adapted from something
like this for test executables from here[1]):

macro (purify exename)
    add_custom_target(purify-${exename})
    add_custom_command(
        TARGET  purify-${exename}
        COMMAND purify
                ${purify_arguments}
                ${EXECUTABLE_OUTPUT_PATH}/${exename}
                ${ARGN}
        WORKING_DIRECTORY
                ${CMAKE_BINARY_DIR}
        COMMENT "Running purify on \"${exename}\"")
    add_dependencies(purify-${exename}
        ${exename})
endmacro (purify)
