It is commonly used by makefile +users in order to install software at non-default location. It is a +basic relocation mechanism that should not be used on Windows (see +CMAKE_INSTALL_PREFIX documentation). It is usually invoked like this: + +:: + + make DESTDIR=/home/john install + +which will install the concerned software using the installation +prefix, e.g. "/usr/local" prepended with the DESTDIR value which +finally gives "/home/john/usr/local". When preparing a package, CPack +first installs the items to be packaged in a local (to the build tree) +directory by using the same DESTDIR mechanism. Nevertheless, if +CPACK_SET_DESTDIR is set then CPack will set DESTDIR before doing the +local install. The most noticeable difference is that without +CPACK_SET_DESTDIR, CPack uses CPACK_PACKAGING_INSTALL_PREFIX as a +prefix whereas with CPACK_SET_DESTDIR set, CPack will use +CMAKE_INSTALL_PREFIX as a prefix. + +Manually setting CPACK_SET_DESTDIR may help (or simply be necessary) +if some install rules uses absolute DESTINATION (see CMake INSTALL +command). However, starting with CPack/CMake 2.8.3 RPM and DEB +installers tries to handle DESTDIR automatically so that it is seldom +necessary for the user to set it. |
