#!
#! macro camitk_library simplifies the declaration of a library inside CamiTK
#! and is to be used for all inner project libraries
#!
#! The name of the CEP library is deduced from the name of the directory, unless LIBNAME is provided
#!
#! If the library is compiled as shared, it adds the needed library properties
#! If it needs relocation flag fPIC (on some plateforms), this macro should determine
#! if this is the case and specify this flag
#!
#! usage:
#! \code
#! camitk_library(
#!     SHARED|STATIC
#!     SOURCES source1.cpp source1.h...
#!     [LIBNAME libname]
#!     [PUBLIC]
#!     [NEEDS_CEP_LIBRARIES lib1 lib2...]
#!     [NEEDS_ITK]
#!     [NEEDS_LIBXML2]
#!     [NEEDS_XERCESC]
#!     [NEEDS_XSD]
#!     [NEEDS_QT]
#!     [DEFINES flag1 flag2 ...]
#!     [EXTERNAL_LIBRARIES lib1 lib2... ]
#!     [INCLUDE_DIRECTORIES dir1 dir2...]
#!     [LINK_DIRECTORIES dir1 dir2...]
#!     [HEADERS_TO_INSTALL]
#!     [CEP_NAME]
#!     [DESCRIPTION]
#!     [EXTRA_TRANSLATE_LANGUAGE]
#!     [CXX_FLAGS flag1 flag2 ...]
#!
#! )
#! \endcode
#!
#! \param SHARED                        optional, if the library should be compiled as shared
#! \param SOURCES                       all sources to be included in the library
#! \param INCLUDE_DIRECTORIES           all needed include directories (${CMAKE_CURRENT_SOURCE_DIR} and ${CMAKE_CURRENT_BINARY_DIR} are automatically added)
#! \param EXTERNAL_LIBRARIES            all the libraries to be used during the link (shared or static)
#! \param NEEDS_CEP_LIBRARIES           all the libraries to be used during the link (shared or static)
#! \param NEEDS_ITK                     add this if your component needs ITK.
#! \param NEEDS_LIBXML2                 add this if the CEP library needs libxml2
#! \param NEEDS_XERCESC                 add this if your action / component needs XercesC library
#! \param NEEDS_XSD                     add this if your action needs Codesynthesis xsd cxx (xml schema compiler)
#! \param NEEDS_QT                      add this if your library depends on Qt 5.x
#! \param LIBNAME                       force the CEP library name to be different from the directory it is in
#! \param LINK_DIRECTORIES              additional directories to use in link_directories(...)
#! \param DEFINES                       list of define flags to add at compilation time
#! \param PUBLIC                        The library is a public library that has to be loaded directly by the operating system.
#!                                      It is generally only needed for SDK library. A public library should not be installed in the
#!                                      lib/${CAMITK_SHORT_VERSION_STRING} but directly in lib/ (on Unix/MacOS) or bin/ (on windows)
#! \param HEADERS_TO_INSTALL            list of header files to install. File would be copied at build and installation time
#!                                      in the ./include/libraries/library-name subdirectory.
#!                                      Note that, if no header files are provided, all header files (*.h) will be install.
#! \param CEP_NAME                      specify the CEP_NAME, which is used to categorized the extension for packaging purpose
#!                                      No CEP_NAME provided will result in default categorization (generic extension).
#! \param DESCRIPTION                   Simple description of the extension. Used for packaging presentation for instance.
#! \param EXTRA_TRANSLATE_LANGUAGE      Additionnal extra language to translate the application
#! \param CXX_FLAGS                 = list of compiler flags to add (such as warning levels (-Wall ...)).
