#
|
|
# Define GNU standard installation directories
|
|
#
|
|
# Provides install directory variables as defined by the
|
|
# `GNU Coding Standards`_.

|
|
# Result Variables
|
|
# ^^^^^^^^^^^^^^^^
|
|
#
|
|
# Inclusion of this module defines the following variables:
|
|
#
|
|
# ``CMAKE_INSTALL_<dir>``
|
|
#
|
|
# Destination for files of a given type. This value may be passed to
|
|
# the ``DESTINATION`` options of :command:`install` commands for the
|
|
# corresponding file type.
|
|
#
|
|
# ``CMAKE_INSTALL_FULL_<dir>``
|
|
#
|
|
# The absolute path generated from the corresponding ``CMAKE_INSTALL_<dir>``
|
|
# value. If the value is not already an absolute path, an absolute path
|
|
# is constructed typically by prepending the value of the
|
|
# :variable:`CMAKE_INSTALL_PREFIX` variable. However, there are some
|
|
# `special cases`_ as documented below.
|
|
#
|
|
# 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``)
|
|
#
|
|
# 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.
|
|
#
|
|
# Special Cases
|
|
# ^^^^^^^^^^^^^
|
|
#
|
|
# The following values of :variable:`CMAKE_INSTALL_PREFIX` are special:
|
|
#
|
|
# ``/``
|
|
#
|
|
# For ``<dir>`` other than the ``SYSCONFDIR`` and ``LOCALSTATEDIR``,
|
|
# the value of ``CMAKE_INSTALL_<dir>`` is prefixed with ``usr/`` if
|
|
# it is not user-specified as an absolute path. For example, the
|
|
# ``INCLUDEDIR`` value ``include`` becomes ``usr/include``.
|
|
# This is required by the `GNU Coding Standards`_, which state:
|
|
#
|
|
# When building the complete GNU system, the prefix will be empty
|
|
# and ``/usr`` will be a symbolic link to ``/``.
|
|
#
|
|
# ``/usr``
|
|
#
|
|
# For ``<dir>`` equal to ``SYSCONFDIR`` or ``LOCALSTATEDIR``, the
|
|
# ``CMAKE_INSTALL_FULL_<dir>`` is computed by prepending just ``/``
|
|
# to the value of ``CMAKE_INSTALL_<dir>`` if it is not user-specified
|
|
# as an absolute path. For example, the ``SYSCONFDIR`` value ``etc``
|
|
# becomes ``/etc``. This is required by the `GNU Coding Standards`_.
|
|
#
|
|
# ``/opt/...``
|
|
#
|
|
# For ``<dir>`` equal to ``SYSCONFDIR`` or ``LOCALSTATEDIR``, the
|
|
# ``CMAKE_INSTALL_FULL_<dir>`` is computed by *appending* the prefix
|
|
# to the value of ``CMAKE_INSTALL_<dir>`` if it is not user-specified
|
|
# as an absolute path. For example, the ``SYSCONFDIR`` value ``etc``
|
|
# becomes ``/etc/opt/...``. This is defined by the
|
|
# `Filesystem Hierarchy Standard`_.
|
|
#
|
|
# .. _`Filesystem Hierarchy Standard`: https://refspecs.linuxfoundation.org/FHS_3.0/fhs/index.html
|
|
#
|
|
# Macros
|
|
# ^^^^^^
|
|
#
|
|
# .. command:: GNUInstallDirs_get_absolute_install_dir
|
|
#
|
|
# ::
|
|
#
|
|
# GNUInstallDirs_get_absolute_install_dir(absvar var)
|
|
#
|
|
# Set the given variable ``absvar`` to the absolute path contained
|
|
# within the variable ``var``. This is to allow the computation of an
|
|
# absolute path, accounting for all the special cases documented
|
|
# above. While this macro is used to compute the various
|
|
# ``CMAKE_INSTALL_FULL_<dir>`` variables, it is exposed publicly to
|
|
# allow users who create additional path variables to also compute
|
|
# absolute paths where necessary, using the same logic.
