34 # LIBS libraries to link with
35 # DEFS compiler defines
36 # EXTRA_CFLAGS additional flags to pass to C compiler
37 # LINKER_SCRIPT linker script
38 # PRE_DEPEND targets required for dependency check
40 # BINARY (/) binary output name (like appname)

51 # STATIC_ONLY set to 'y' if binary cannot be linked dynamically

56 # LSONAME Soname / name with short version, e.g. libfoo.so.0
58 # (x) required variables
59 # (/) exactly one of the variables must be defined
