# - Define GNU standard installation directories
# Provides install directory variables as defined for GNU software:
#  http://www.gnu.org/prep/standards/html_node/Directory-Variables.html
# Inclusion of this module defines the following variables:
#  CMAKE_INSTALL_<dir>      - destination for files of a given type
#  CMAKE_INSTALL_FULL_<dir> - corresponding absolute path
# where <dir> is one of:
#  BINDIR           - user executables (bin)
#  SBINDIR          - system admin executables (sbin)
#  LIBEXECDIR       - program executables (libexec)
#  SYSCONFDIR       - read-only single-machine data (etc)
#  SHAREDSTATEDIR   - modifiable architecture-independent data (com)
#  LOCALSTATEDIR    - modifiable single-machine data (var)
#  LIBDIR           - object code libraries (lib or lib64 or lib/<multiarch-tuple> on Debian)
#  INCLUDEDIR       - C header files (include)
#  OLDINCLUDEDIR    - C header files for non-gcc (/usr/include)
#  DATAROOTDIR      - read-only architecture-independent data root (share)
#  DATADIR          - read-only architecture-independent data (DATAROOTDIR)
#  INFODIR          - info documentation (DATAROOTDIR/info)
#  LOCALEDIR        - locale-dependent data (DATAROOTDIR/locale)
#  MANDIR           - man documentation (DATAROOTDIR/man)
#  DOCDIR           - documentation root (DATAROOTDIR/doc/PROJECT_NAME)
# Each CMAKE_INSTALL_<dir> value may be passed to the DESTINATION options of
# install() commands for the corresponding file type.  If the includer does
# not define a value the above-shown default will be used and the value will
# appear in the cache for editing by the user.
# Each CMAKE_INSTALL_FULL_<dir> value contains an absolute path constructed
# from the corresponding destination by prepending (if necessary) the value
# of CMAKE_INSTALL_PREFIX.
