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