You might be confused as in that link, there are two CPPFLAGS defined in the same file. The -install option requires CMake 3.15 or later though. not using CPack), then you can use a command of the following form to install just the component you want: cmake -install /path/to/build/dir -components M圜omp. Linking path and include paths have to be specified as per the opencv version you want.įor example : You have opencv 2.4.9 installed in /path/to/opencv2.4.9/lib/ and opencv 3.0.0 install in /path/to/opencv3.0.0/lib/ as per mentioned in that link, you will have makefile as per below: If you are invoking an install and creating packages manually (i.e. DCMAKE_INSTALL_PREFIX=/path/to/opencv3.0.0ĭo not confuse this path with source path.Īnd then real "magic" is in the makefile to compile your own code. DCMAKE_INSTALL_PREFIX=/path/to/opencv2.4.9/ After a while, it becomes apparent that MYINSTALL is a variable prefix and cmakeparsearguments will parse options (which in this case are value-less keywords or nullary keywords or whatever you want to call a set of flags), one value arguments - name is self explaining, in case of this example it’ll be i.e DESTINATION, and. Config-file packages are provided by upstream vendors as part of development packages, that is, they belong with the header files and any other files provided to assist downstreams in using the. For example, you should specify different install paths using -DCMAKE_INSTALL_PREFIX= flag. The most simple way for a CMake user to tell cmake(1) to search in a non-standard prefix for a package is to set the CMAKEPREFIXPATH cache variable. You should have different paths while "cmaking" it.
