Why not use the COMPONENT feature of the various install command signatures
to separate your installables into components...?

Then you can run:
  cd binary_dir
  cmake -D COMPONENT=MyComponent -P cmake_install.cmake
and that will run just the install rules associated with the COMPONENT
MyComponent...

You could even add a custom target named "install_my_component" to do this
via "make install_my_component" if you like...

HTH,
