CMake's built-in `GNUInstallDirs` module defines the `CMAKE_INSTALL_DOCDIR`, `CMAKE_INSTALL_INFODIR` and `CMAKE_INSTALL_MANDIR` variables as the installation paths for generic documentation, info pages and man pages respectively. Define Slackware-friendly default values for these variables - `/usr/doc`, `/usr/info` and `/usr/man` respectively - rather than the typical directories beneath `/usr/share`.

If a relative path is given for any of these variables, the computed installation path is relative to CMAKE_INSTALL_PREFIX, as documented in /usr/share/cmake-*/Modules/GNUInstallDirs.cmake.

This is perhaps more contentious. Sourcegraph suggests that the built-in CMAKE_INSTALL_MANDIR is much more widely used than MAN_INSTALL_DIR - 9.2k results vs 1.5k. I'd say MAN_INSTALL_DIR should be defined for projects that don't use the built-in variable.
