As others have replied you can use scenario variables.
And they are passed from commandline.
But gprbuild looks for variables passed in with -X like -XVARIBLE=Value
however if that is not found it will look for that name amomg the
environent variables
so I create env vars for current os/arch/db in the os
and test on every combination needed
db_libs := ();
case db is
when Oracle => db_libs := db_lib1;
when Postgresql => db_libs := db_lib2;
when sqlserver => db_libs := db_lib3;
end case
other_libs := ():
case os_arch is
when AIX_PPC => other_libs := lib1;
when Linux_x64 => other_libs := lib2;
when Linux_arm => other_libs := lib3;
when Win_64 => other_libs := lib4;
end case
and so on
the use db_libs and other-libs elsewhere in the gprfile
