#
#=============================================================================

# 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_FORCE_OLD_STREAMS = 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_FORCE_OLD_STREAMS 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.
