# - 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.
