I generating `profaw` file with compiler option. If I run the executable, the executable will generate every time `profraw` file. I wanted to automate this process

This way it perfectly works for executing twice the executable automatically.

```cmake
add_custom_command(TARGET ${EXECUTABLE_NAME} POST_BUILD 
                COMMAND ${CMAKE_COMMAND} -E echo " 2. Execution of: ${EXECUTABLE_NAME}"
                COMMAND $<TARGET_FILE:${EXECUTABLE_NAME}>
                COMMAND ${CMAKE_COMMAND} -E sleep 1
                
                COMMAND ${CMAKE_COMMAND} -E echo " 2. Execution of: ${EXECUTABLE_NAME}"
                COMMAND $<TARGET_FILE:${EXECUTABLE_NAME}>
                COMMAND ${CMAKE_COMMAND} -E sleep 1)

```

However I wanted to do run arbitrary number of times the executable so I wrote this command. However there’s 2 problems

1. The command executing always twice as much the given number. For example I set **SET\_PROFRAW\_COUNT** to 5 so it will execute 10 times
2. Generated profraw files are highly corrupted and non-functional

```cmake
set(SET_PROFRAW_COUNT 5)

    #Geneate the string for number of times executing the command 
    math(EXPR SET_PROFRAW_COUNT "${SET_PROFRAW_COUNT} -1") ##This is required because foreach executing 0-5 5th inclusive
    set(COMMAND_LIST "")
    foreach (i RANGE ${SET_PROFRAW_COUNT})
        LIST(APPEND COMMAND_LIST
                COMMAND ${CMAKE_COMMAND} -E echo " ${i}. Execution of: ${EXECUTABLE_NAME}"
                COMMAND $<TARGET_FILE:${EXECUTABLE_NAME}>
                COMMAND ${CMAKE_COMMAND} -E sleep 1)
    endforeach ()

    add_custom_command(TARGET ${EXECUTABLE_NAME} POST_BUILD ${COMMAND_LIST}

```
