Install Step The INSTALL_DIR is underneath the calling project’s binary directory. Use INSTALL_DIR to specify a different location. Note that in addition to setting INSTALL_DIR, you also have to pass -DCMAKE_INSTALL_PREFIX or --prefix to the CMake or configure command. It is not used automatically in the configure step since not all projects follow this convention.
