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. +# +# DEFINITIONS +# A list of symbols to be used for conditional compilation. They are the same +# as they would be passed using the valac "--define=" option. +# +# 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 a 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) +# include(${VALA_USE_FILE}) +# +# vala_precompile(VALA_C +# SOURCES +# 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. +## + +## +# Copyright 2009-2010 Jakob Westhoff.
