##
# Compile vala files to their c equivalents for further processing.
#
# The "vala_precompile" macro takes care of calling the valac executable on the
# given source to produce c files which can then be processed further using
# default cmake functions.
#
# The first parameter provided is a variable, which will be filled with a list
# of c files outputted by the vala compiler. This list can than be used in
# conjuction with functions like "add_executable" or others to create the
# neccessary compile rules with CMake.
#
# The initial variable is followed by a list of .vala files to be compiled.
# Please take care to add every vala file belonging to the currently compiled
# project or library as Vala will otherwise not be able to resolve all
# dependencies.
#
# The following sections may be specified afterwards to provide certain options
# to the vala compiler:
#
# PACKAGES
# A list of vala packages/libraries to be used during the compile cycle. The
# package names are exactly the same, as they would be passed to the valac
# "--pkg=" option.
#
# OPTIONS
# A list of optional options to be passed to the valac executable. This can be
# used to pass "--thread" for example to enable multi-threading support.
#
# CUSTOM_VAPIS
# A list of custom vapi files to be included for compilation. This can be
# useful to include freshly created vala libraries without having to install
# them in the system.
#
# GENERATE_VAPI
# Pass all the needed flags to the compiler to create an internal vapi for
# the compiled library. The provided name will be used for this and a
# <provided_name>.vapi file will be created.
#
# GENERATE_HEADER
# Let the compiler generate a header file for the compiled code. There will
# be a header file as well as an internal header file being generated called
# <provided_name>.h and <provided_name>_internal.h
#
# GENERATE_GIR
# Have the compiler generate a GObject-Introspection repository file with
# name: <provided_name>.gir. This can be later used to create a binary typelib
# using the GI compiler.
#
# GENERATE_SYMBOLS
# Output a <provided_name>.symbols file containing all the exported symbols.
#
# The following call is a simple example to the vala_precompile macro showing
# an example to every of the optional sections:
#
# vala_precompile(VALA_C mytargetname
# source1.vala
# source2.vala
# source3.vala
# PACKAGES
# gtk+-2.0
# gio-1.0
# posix
# DIRECTORY
# gen
# OPTIONS
# --thread
# CUSTOM_VAPIS
# some_vapi.vapi
# GENERATE_VAPI
# myvapi
# GENERATE_HEADER
# myheader
# GENERATE_GIR
# mygir
# GENERATE_SYMBOLS
# mysymbols
# )
#
# Most important is the variable VALA_C which will contain all the generated c
# file names after the call.
