#.rst: # GNUInstallDirs # -------------- # # 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_ - destination for files of a given type # CMAKE_INSTALL_FULL_ - corresponding absolute path # # where 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/ 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_ 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_ value contains an absolute path constructed # from the corresponding destination by prepending (if necessary) the # value of CMAKE_INSTALL_PREFIX. #============================================================================= # Copyright 2011 Nikita Krupen'ko # Copyright 2011 Kitware, Inc. # # Distributed under the OSI-approved BSD License (the "License"); # see accompanying file Copyright.txt for details. # # This software is distributed WITHOUT ANY WARRANTY; without even the # implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. # See the License for more information. #============================================================================= # (To distribute this file outside of CMake, substitute the full # License text for the above reference.) # Installation directories # if(NOT DEFINED CMAKE_INSTALL_BINDIR) set(CMAKE_INSTALL_BINDIR "bin" CACHE PATH "user executables (bin)") endif() if(NOT DEFINED CMAKE_INSTALL_SBINDIR) set(CMAKE_INSTALL_SBINDIR "sbin" CACHE PATH "system admin executables (sbin)") endif() if(NOT DEFINED CMAKE_INSTALL_LIBEXECDIR) set(CMAKE_INSTALL_LIBEXECDIR "libexec" CACHE PATH "program executables (libexec)") endif() if(NOT DEFINED CMAKE_INSTALL_SYSCONFDIR) set(CMAKE_INSTALL_SYSCONFDIR "etc" CACHE PATH "read-only single-machine data (etc)") endif() if(NOT DEFINED CMAKE_INSTALL_SHAREDSTATEDIR) set(CMAKE_INSTALL_SHAREDSTATEDIR "com" CACHE PATH "modifiable architecture-independent data (com)") endif() if(NOT DEFINED CMAKE_INSTALL_LOCALSTATEDIR) set(CMAKE_INSTALL_LOCALSTATEDIR "var" CACHE PATH "modifiable single-machine data (var)") endif() # We check if the variable was manually set and not cached, in order to # allow projects to set the values as normal variables before including # GNUInstallDirs to avoid having the entries cached or user-editable.
