Building a single component app or sim

[jlucas9]

As we look forward into better configurations for both missions and spacecraft levels in NOS3, the ability to be able to just build a single application or simulator after changes instead of the entire suite (FSW, SIM) could significantly reduce iteration time during development of these pieces.

Possibly related to #134

From the latest dev branch 3fa685d.

FSW

• make
• make debug
  • cd ./fsw/build/amd64-linux-gnu/default_cpu1/apps/arducam/fsw
  • make clean
  • make
    The above appears to be able to clean and remake the specific application in question. Can we do this without already having everything built?
• make clean
• make config
• make debug
  • cd ./fsw/build
  • cmake ../cfe
  • cd ./amd64-linux-gnu/default_cpu1/apps/arducam/fsw
  • make
  • make clean
    Note that playing with the CF app, it doesn't have the same 'fsw' final folder and also requires ./tools/elf2cfetbl to be built prior.

SIM

• make debug
  • mkdir ./sims/build
  • cd ./sims/build
  • cmake ..
  • cd arducam
  • make
  • make clean
    It seems that additional dependencies like sim_common were built automatically.
