| CPACK_PACKAGING_INSTALL_PREFIX | |
| ------------------------------ | |
| The prefix used in the built package. | |
| Each CPack generator has a default value (like /usr). This default | |
| value may be overwritten from the CMakeLists.txt or the cpack command | |
| line by setting an alternative value. | |
| e.g. set(CPACK_PACKAGING_INSTALL_PREFIX "/opt") | |
| This is not the same purpose as CMAKE_INSTALL_PREFIX which is used | |
| when installing from the build tree without building a package. |
