# To compile Vala sources, define a target using Autotools standard variable
# using target_BIN or lib_LTLIBRARIES to $(VALA_TARGET).
# All Vala sources should be defined in VALASOURCES, as result
# you have to set your target sources to target_SOURCES = $(VALA_CSOURCES).
#
# Use standard Autotools variables to set CFLAGS, LDFLAGS and LIBADD, as required.
