+#
+# Copyright (c) 2010 Daniel Pfeifer <daniel@pfeifer-mail.de>

+#
+# Creates source debian files and manages library dependencies
+#
+# Features:
+# 
+# - Automatically generates symbols and run-time dependencies from the build dependencies
+# - Custom copy of source directory via CPACK_DEBIAN_PACKAGE_SOURCE_COPY
+# - Simultaneous output of multiple debian source packages for each distribution
+# - Can specificy distribution-specific dependencies by suffixing DEPENDS with _${DISTRO_NAME}, for example: CPACK_DEBIAN_PACKAGE_DEPENDS_LUCID, CPACK_COMPONENT_MYCOMP0_DEPENDS_LUCID
+#
+# Usage:
+#
+# set(CPACK_DEBIAN_BUILD_DEPENDS debhelper cmake)
+# set(CPACK_DEBIAN_PACKAGE_PRIORITY optional)

+#
+# This module sets:
+#
+# ::
+#
+#    IL_LIBRARIES -   the name of the IL library. These include the full path to
+#                     the core DevIL library. This one has to be linked into the
+#                     application.
+#    ILU_LIBRARIES -  the name of the ILU library. Again, the full path. This
+#                     library is for filters and effects, not actual loading. It
+#                     doesn't have to be linked if the functionality it provides
+#                     is not used.
+#    ILUT_LIBRARIES - the name of the ILUT library. Full path. This part of the
+#                     library interfaces with OpenGL. It is not strictly needed
+#                     in applications.
+#    IL_INCLUDE_DIR - where to find the il.h, ilu.h and ilut.h files.
+#    IL_FOUND -       this is set to TRUE if all the above variables were set.
+#                     This will be set to false if ILU or ILUT are not found,
+#                     even if they are not needed. In most systems, if one
+#                     library is found all the others are as well. That's the
+#                     way the DevIL developers release it.
