I don't know of a way to control what gets installed by "make install", 
but you can use custom targets to provide your own alternative behaviors 
- for example, I used the following to install debug and release 
versions of a single component (out of many) on a Win32 project where I 
was doing a lot of debugging:

ADD_CUSTOM_TARGET(Install-Foo-Debug
   ${CMAKE_COMMAND}
   -D "BUILD_TYPE=Debug"
   -D "CMAKE_INSTALL_COMPONENT=Foo"
   -D "CMAKE_INSTALL_PREFIX=C:/Program Files/Foo-Debug"
   -P "${Foo_BINARY_DIR}/cmake_install.cmake"
   )

ADD_CUSTOM_TARGET(Install-Foo-Release
   ${CMAKE_COMMAND}
   -D "BUILD_TYPE=Release"
   -D "CMAKE_INSTALL_COMPONENT=Foo"
   -D "CMAKE_INSTALL_PREFIX=C:/Program Files/Foo"
   -P "${Foo_BINARY_DIR}/cmake_install.cmake"
   )

Cheers,
Tim
