I have a GNAT cross-toolchain setup that works fine.  I have been using a g=
eneric project file named default.gpr, which gprbuild will use automaticall=
y, in my project directory.  So the command for a native compile is:

gprbuild -p  test_adc

And the command for a cross-compile for a Raspberry Pi 4 target is:

gprbuild -p --config=3D/usr/local/gcc-aarch64-linux-gnu-muntsos-crosstool/s=
hare/gpr/aarch64-linux-gnu.cgpr test_adc

For working from the command line, passing --config=3Dblah to gprbuild to s=
elect cross-compilation works perfectly well.  But when using gps, it isn't=
 quite as convenient.  Is there some way to move --config=3Dblah from the g=
prbuild command line to the project file?

I've looked through the gprbuild documentation but haven't found any obviou=
s way to accomplish this.  The Target attribute doesn't quite work, as my c=
ross-compilation .cgpr files are not in a place known to gprbuild, and I'd =
rather not mess with environment variables with gps.
