This variable defaults to +/usr/local on UNIX and c:/Program Files on Windows. + +On UNIX one can use the DESTDIR mechanism in order to relocate the +whole installation. DESTDIR means DESTination DIRectory. It is +commonly used by makefile users in order to install software at +non-default location. 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". + +WARNING: DESTDIR may not be used on Windows because installation +prefix usually contains a drive letter like in "C:/Program Files" +which cannot be prepended with some other prefix. + +The installation prefix is also added to CMAKE_SYSTEM_PREFIX_PATH so +that find_package, find_program, find_library, find_path, and +find_file will search the prefix for other software. |
