# @brief Set of macros used by akantu to handle the package system
#
# @section DESCRIPTION
#
# This package defines multiple function to handle packages. This packages can
# be of two kinds regular ones and extra_packages (ex: in akantu the LGPL part
# is regular packages and extra packages are on Propetary license)
#
# Package are loaded with the help of the command:
# package_list_packages(<regular_package_folder>
# [ EXTRA_PACKAGE_FOLDER <extra_package_folder> ]
# [ SOURCE_FOLDER <source_folder>]
# [ TEST_FOLDER <test_folder> ]
# [ MANUAL_FOLDER <manual_folder> ]
# )
#
# This command will look for packages name like
# <regular_package_folder>/<package>.cmake
# OR <extra_package_folder>/<package>/package.cmake
#
# A package is a cmake script that should contain at list the declaration of a
# package
#
# package_declare(<package real name>
# [EXTERNAL] [META] [ADVANCED] [NOT_OPTIONAL]
# [DESCRIPTION <description>] [DEFAULT <default_value>]
# [DEPENDS <pkg> ...]
# [BOOST_COMPONENTS <pkg> ...]
# [EXTRA_PACKAGE_OPTIONS <opt> ...]
# [COMPILE_FLAGS <flags>]
# [SYSTEM <bool> [ <script_to_compile> ]])
#
# It can also declare multiple informations:
# source files:
# package_declare_sources(<package real name>
# <src1> <src2> ... <srcn>)
#
# a LaTeX documentation:
# package_declare_documentation(<package real name>
# <line1> <line2> ...<linen>)
#
# LaTeX documentation files
# package_declare_documentation_files(<package real name>
# <file1> <file2> ... <filen>)
#
# Different function can also be retrieved from the package system by using the
# different accessors
# package_get_name(<pkg> <retval>)
# package_get_real_name(<pkg> <retval>)
#
# package_get_option_name(<pkg> <retval>)

#
# package_get_compile_flags(<pkg> <retval>)
#
# package_get_include_dir(<pkg> <retval>)

#
# package_get_libraries(<pkg> <retval>)
# package_set_libraries(<pkg> <lib1> <lib2> ... <libn>)
#
# package_add_extra_dependency(pkg <dep1> <dep2> ... <depn>)

# package_get_extra_dependencies(<pkg> <retval>)
#

# package_is_deactivated(<pkg> <retval>)
#
# package_get_dependencies(<pkg> <retval>)
# package_add_dependencies(<pkg> <dep1> <dep2> ... <depn>)
#
# package_get_all_source_files(<srcs> <public_headers> <private_headers>)
# package_get_all_include_directories(<inc_dirs>)
# package_get_all_external_informations(<include_dir> <libraries>)
# package_get_all_definitions(<definitions>)
