#
# Common build variable values for folks backend libraries.
#
# Required variables:
#  - BACKEND_NAME = name-of-backend
#    (this must be the same as the source directory and the backend's type ID)
#  - BACKEND_NAME_C = NameOfBackend
#    (BACKEND_NAME in CamelCase for the GIR filename)
#  - BACKEND_API_VERSION = $(FOLKS_something_API_VERSION)
#  - BACKEND_LT_VERSION = $(FOLKS_something_LT_VERSION)
#    (from configure.ac)
#  - BACKEND_SYMBOLS_REGEX = something
#    (regex to pass to -export-symbols-regex to determine the backend’s public
#     symbols)
#  - BACKEND_NAMESPACE = Something
#    (Vala namespace used in the backend code)
# Required targets:
#  - libfolks-$(BACKEND_NAME).la
# Derived helper variables (these may be overridden for weird backends):
#  - BACKEND_LIBRARY_NAME
#  - BACKEND_LA_FILE
#  - BACKEND_PC_FILE
#  - BACKEND_GIR_FILE
#  - BACKEND_VAPI_FILE
#  - BACKEND_DEPS_FILE
#  - BACKEND_HEADER_FILE
# Defined backend library variables (these must be included in the
# backend-specific variables):
#  - backend_library_sources
#  - backend_library_valaflags
#  - backend_library_cppflags
#  - backend_library_cflags
#  - backend_library_libadd
#  - backend_library_ldflags
# in addition, most of these have *_generic variants which don’t include
# backend-specific flags (for use in helper and utility libraries).
# The defined variables include flags for the standard dependencies:
#  - folks
#  - GIO
#  - GLib
#  - libgee
# and also include the relevant $(AM_*) variables.
#
# Additional rules are included for generating and installing the following:
#  - pkg-config
#  - VAPI and deps files
#  - C header file
#  - GIR and typelib files

# Derived (but still overrideable) variables
