| CMAKE_INSTALL_PREFIX |
| -------------------- |
| |
| Install directory used by :command:`install`. |
| |
| If ``make install`` is invoked or ``INSTALL`` is built, this directory is |
| prepended onto all install directories. This variable defaults to |
| ``/usr/local`` on UNIX and ``c:/Program Files/${PROJECT_NAME}`` on Windows. |
| See :variable:`CMAKE_INSTALL_PREFIX_INITIALIZED_TO_DEFAULT` for how a |
| project might choose its own default. |
| |
| On UNIX one can use the ``DESTDIR`` mechanism in order to relocate the |
| whole installation. See :envvar:`DESTDIR` for more information. |
| |
| The installation prefix is also added to :variable:`CMAKE_SYSTEM_PREFIX_PATH` |
| so that :command:`find_package`, :command:`find_program`, |
| :command:`find_library`, :command:`find_path`, and :command:`find_file` |
| will search the prefix for other software. |
| |
| .. note:: |
| |
| Use the :module:`GNUInstallDirs` module to provide GNU-style |
| options for the layout of directories within the installation. |
