sample_defs/tables source files won't compile without table header file include

[jmahoney-dev]

Describe the bug
If we want to put all tables source files in global *_defs directory in a tables dir inside *_defs they need to be able to access *_table.h which would be in the respective app's src directory.

To Reproduce
Steps to reproduce the behavior:

1. Create directory in sample_defs called "tables"
2. Move sample_table.c into sample_defs/tables directory
3. Build cFS (make SIMULATION=native prep, make)
4. Build will fail because sample_table.c can't find sample_table.h

Expected behavior
Need to be able to provide includes to sample_defs/tables. As a "hack" I add a "include_directories(fsw/src)" in CMakeLists.txt in apps/sample_app which allows sample_table.c to compile from sample_defs/tables.

System observed on:

• Linux Ubuntu 18.04 LTS
• Native linux cFS build
• Versions cFE 6.7.14, OSAL 5.0.13, PSP 1.4.10

Your "hack" is actually the exact same thing I did recently. Could use an interface library also.
