Add integration instructions

For a new user, it would be very helpful to include some instructions in README.md on how to add the skeleton_app to nasa/cFS. I have not been able to get it working.

I simply tried to duplicate all of the lines that referenced sample_app and apply them to skeleton_app. The result is in this repo and summarized below.

  1. Add #include "skeleton_app_msgids.h in sch_lab_sched_tab.h
  2. Add {CFE_SB_MSGID_WRAP_VALUE(SKELETON_APP_SEND_HK_MID), 4}, to SCH_TBL_Structure.Config in sch_lab_table.c
  3. Add include_directories(${skeleton_app_MISSION_DIR}/fsw/platform_inc) to apps/sch_lab/CMakeLists.txt
  4. Add {CFE_SB_MSGID_WRAP_VALUE(SKELETON_APP_HK_TLM_MID), {0, 0}, 4}, to TO_LAB_Subs.Subs, and include associated header, in to_lab_sub.c
  5. Add include_directories(${skeleton_app_MISSION_DIR}/fsw/platform_inc) to apps/to_lab/CMakeLists.txt
  6. Duplicate sample_app line for skeleton_app in cpu1_cfe_es_startup.scr
  7. Add skeleton_app to list in targets.cmake
  8. Make message IDs in skeleton_app_msgids.h unique

After making these changes, the program builds successfully. But when running ./core-cpu1, the skeleton_app fails with the following messages.

Skeleton_app creation

Hello I am a student who wants to add the skeleton app to my cFS.

I git clone skeleton app to the apps file path and populated the other necessary file paths needed for sample apps creation and there were still issues.

I implemented the changes noted in the issue logs such as the CCSDS_CommandPacket_t #4 changes and followed #2 "Add integration instructions" 's changes for how they got it working however I tend to run into errors. Some examples include what is shown in the reply below.

Is there a guide for a noob like me to integrate the app onto cfs. NASA has such robust and great documentation but i still havent managed. Am i not placing the app name in the correct locations? Am i missing commands i should be running? full breakdown for a beginner plz.
