Add CPS examples as below:

cps-examples/
└── examples/
    ├── libbar.cps
    ├── libexample.cps
    └── libfoo.cps

Thank you for your interest!

However, there are several major problems with your examples:

1. Version 0.9 is quite old. Please target the current version 0.13.
2. Please use JSON, not YAML. While CPS itself does not specify a transport, JSON is the de facto standard. YAML is much more difficult to parse.
3. Most of your examples have serious deviations from the specification.
4. Direct use of compile/link flags is strongly discouraged.

@mwoehlke-kitware Thanks for reviewing it, please take a look again to see if that's better or anything can be added.

[mwoehlke-kitware]

Better, but there are still some schema-conformance issues. (Note: comments on 'libbar' may apply to other examples.)

[mwoehlke-kitware]

Since you are hand-crafting these, please also validate them against the machine-readable schema.

@mwoehlke-kitware ok I just used https://www.jsonschemavalidator.net/ to validate these files and all looks good except link_location.

[mwoehlke-kitware]

Thanks.

all looks good except link_location.

That's a false report; the current version of the schema doesn't understand that optional attributes may be null. cps-org/cps#93 hopefully fixes that.
