1CPACK_PACKAGING_INSTALL_PREFIX 2------------------------------ 3 4The prefix used in the built package. 5 6Each CPack generator has a default value (like ``/usr``). This default 7value may be overwritten from the ``CMakeLists.txt`` or the :manual:`cpack(1)` 8command line by setting an alternative value. Example: 9 10:: 11 12 set(CPACK_PACKAGING_INSTALL_PREFIX "/opt") 13 14This is not the same purpose as :variable:`CMAKE_INSTALL_PREFIX` which is used 15when installing from the build tree without building a package. 16
