cmdoption-cmake-install-component does not help to get list of possible components to install

bash-5.3$ cmake --install . --component
CMake Error: Invalid value used with --component
Usage: cmake --install <dir> [options]
Options:
  <dir>              = Project binary directory to install.
  --config <cfg>     = For multi-configuration tools, choose <cfg>.
  --component <comp> = Component-based install. Only install <comp>.
  --default-directory-permissions <permission> 
     Default install permission. Use default permission <permission>.
  -j <jobs> --parallel <jobs>
     Build in parallel using the given number of jobs. 
     The CMAKE_INSTALL_PARALLEL_LEVEL environment variable
     specifies a default parallel level when this option is not given.
  --prefix <prefix>  = The installation prefix CMAKE_INSTALL_PREFIX.
  --strip            = Performing install/strip.
  -v --verbose       = Enable verbose output.

bash-5.3$ cmake --install . --component .
-- Install configuration: "Release"
bash-5.3$

I would help to get all possible component names to install instead of this output.
