First you should use the COMPONENT parameter of the INSTALL command.
See:
cmake --help-command install
and
http://www.cmake.org/Wiki/CMake:Component_Install_With_CPack

then you may install all the target/files/... belonging to a
particular component by doing:

cd buildir
cmake -DCOMPONENT="componentname" -P cmake_install.cmake
