And OP has two projects, and the log he supplies shows that gnatmake has
correctly decided to

  * compile the test program using the test gpr
  * build the library using the library gpr
  * link the test program.using the test gpr

This is standard behaviour (now, at any rate; it may well have been less
helpful in the past ...); I don't see where the failures are coming
from.
