# Program: KWSys - Kitware System Library
# Module: $RCSfile$
#
# Copyright (c) Kitware, Inc., Insight Consortium. All rights reserved.

#
#=============================================================================
# The Kitware System Library is intended to be included in other
# projects. It is completely configurable in that the library's
# namespace can be configured and the components that are included can
# be selected invididually.
# Typical usage is to import the kwsys directory tree into a
# subdirectory under a parent project and enable the classes that will
# be used. All classes are disabled by default. The CMake listfile
# above this one configures the library as follows:
#
# SET(KWSYS_NAMESPACE foosys)
# SET(KWSYS_USE_Directory 1) # Enable Directory class.
# SUBDIRS(kwsys)
#
# Optional settings are as follows:
#
# KWSYS_HEADER_ROOT = The directory into which to generate the kwsys headers.
# A directory called "${KWSYS_NAMESPACE}" will be
# created under this root directory to hold the files.
#
# Example:
#
# SET(KWSYS_HEADER_ROOT ${PROJECT_BINARY_DIR})
# INCLUDE_DIRECTORIES(${PROJECT_BINARY_DIR})
#
# KWSYS_LIBRARY_INSTALL_DIR = The installation target directories into
# KWSYS_HEADER_INSTALL_DIR which the libraries and headers from
# kwsys should be installed by a "make install".
# The values should be specified relative to
# the installation prefix and start with a '/'.
# Example:
#
# SET(KWSYS_LIBRARY_INSTALL_DIR /lib)
# SET(KWSYS_HEADER_INSTALL_DIR /include)
#
# KWSYS_IOS_FORCE_OLD = Force use of old non-ANSI C++ streams even if
# new streams are available. This may be used
# by projects that cannot configure their
# streams library.
# Example:
#
# SET(KWSYS_IOS_FORCE_OLD 1)
#
# Once configured, kwsys should be used as follows from C or C++ code:
#
# #include <foosys/Directory.hxx>
# ...
# foosys::Directory directory;
#
#-----------------------------------------------------------------------------

# This should be the case only when kwsys is not included inside
# another project and is being tested.
