# Compiling and linking against in tree libraries.
#
# In order to compile and link against an in-tree library various
# cpp/compiler/linker options are required.
#
# For example consider a library "libfoo" which itself uses two other
# libraries:
# libbar - whose use is entirely internal to libfoo and not exposed
# to users of libfoo at all.
# libbaz - whose use is entirely internal to libfoo but libfoo's
# public headers include one or more of libbaz's
# public headers. Users of libfoo are therefore transitively
# using libbaz's header but not linking against libbaz.
#
# SHLIB_libfoo: Flags for recursively linking against libfoo. Must
# contains $(call xenlibs-rpath,foo) and:
# -Wl,-rpath-link=<directory containing libfoo.so>
#
# CFLAGS_libfoo: Flags for compiling against libfoo. Must add the
# directories containing libfoo's headers to the
# include path. Must recursively include
# $(CFLAGS_libbaz), to satisfy the transitive inclusion
# of the headers but not $(CFLAGS_libbar) since none of
# libbar's headers are required to build against
# libfoo.
#
# LDLIBS_libfoo: Flags for linking against libfoo. Must contain
# $(call xenlibs-rpath,foo) and the path to libfoo.so
#
# Consumers of libfoo should include $(CFLAGS_libfoo) and
# $(LDLIBS_libfoo) in their appropriate directories. They should not
# include any CFLAGS or LDLIBS relating to libbar or libbaz unless
# they use those libraries directly (not via libfoo) too.
# Give the list of Xen library that the libraries in $(1) are linked against,
