See Projucer compiler commands and output

The project I am working on compiles with no issues in Xcode, but it blows up with pre-processor errors in projucer. I am sure it is something simple like a missing option, but the messages shown in projucer do not point me in any direction.

Is there some way to see the compiler commands and raw output from the projucer build? That would let me compare what is being done differently.
