Core Build project without binaries. (#959)

Do not check for binaries in the project directory if the user defined
a binary in the Main tab. This supports the case where the user
disables auto build and selects a binary outside the project directory.
Otherwise the binaries check would stop the launch with the message
that no binaries are found in the project.
