+#  VALA_EXECUTABLE  Full path to the valac executable if it has been found
+#  VALA_VERSION     Version number of the available valac
+#  VALA_USE_FILE    Include this file to define the vala_precompile function

+# Compile vala files to their c equivalents for further processing.
+#
+# The "vala_precompile" function 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 following sections may be specified afterwards to provide certain options
+# to the vala compiler:
+#
+# SOURCES
+#   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.
+#
+# 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
+#
+# The following call is a simple example to the vala_precompile macro showing
+# an example to every of the optional sections:
+#
+#   find_package(Vala "0.12" REQUIRED)
+#   inlcude(${VALA_USE_FILE})
+#
+#   vala_precompile(VALA_C
+#     SOURCES
+#       source1.vala
+#       source2.vala
+#       source3.vala
+#     PACKAGES
+#       gtk+-2.0
+#       gio-1.0
+#       posix

+#       myvapi
+#     GENERATE_HEADER
+#       myheader
+#     )
+#
+# Most important is the variable VALA_C which will contain all the generated c
+# file names after the call.
