Error: DCAP-PCKRetrieval Sample Code Example not running

I tried to run the `dcap-pckretrieval` sample code example but encountered an error during the `make` command execution. I have also tried to use the Dockerfile provided in the README, but it threw an error when creating the image with the file.

Error log:

error: could not compile `PCKIDRetrievalTool` due to previous error
make: *** [Makefile:137: bin/PCKIDRetrievalTool] Error 101
root@63ba5807b7f6:~/sgx/samplecode/dcap-pckretrieval#
```

I'm getting a very similar error when attempting to "make" my own application.

Reproduce the failure from samplecode/dcap-pckretrieval with the README Dockerfile and inspect Makefile:137 plus the app build configuration. Start with the linker output showing that sgx_dcap_ql cannot be found, then compare the sample and the user's application setup. Done means the sample builds successfully and the documented Docker image can be created.
