| #Goal for this example: |
| # 1. Build two static libraries that defines multiple methods and kernels |
| # 2. Resolve the device symbols into the second static library, therefore |
| # confirming that the first static library is on the device link line |
| # 3. Verify that we can't use those device symbols from anything that links |
| # to the static library |
