You will need to create an "install" command that copies the library
into the runtime directory. There are lots of examples in the email
archives. Here is what I do for the Qt libraries:

if (AIM_BUILD_QT_APPS AND NOT Q_WS_MAC)
     if (DEFINED QT_QMAKE_EXECUTABLE)
         SET (QTLIBLIST QtCore QtGui)

         IF (MSVC)
             set(TYPE "d")
             FOREACH(qtlib ${QTLIBLIST})
               IF (WIN32)
                 GET_FILENAME_COMPONENT(QT_DLL_PATH_tmp $
{QT_QMAKE_EXECUTABLE} PATH)
                 file(MAKE_DIRECTORY ${CMAKE_RUNTIME_OUTPUT_DIRECTORY}/
Debug)
                 file(MAKE_DIRECTORY ${CMAKE_RUNTIME_OUTPUT_DIRECTORY}/
Release)
                 file(MAKE_DIRECTORY ${CMAKE_RUNTIME_OUTPUT_DIRECTORY}/
MinSizeRel)
                 file(MAKE_DIRECTORY ${CMAKE_RUNTIME_OUTPUT_DIRECTORY}/
RelWithDebInfo)
                 INSTALL(FILES ${QT_DLL_PATH_tmp}/${qtlib}${type}d4.dll
                     DESTINATION ./
                     CONFIGURATIONS Debug
                     COMPONENT Applications)
                 INSTALL(FILES ${QT_DLL_PATH_tmp}/${qtlib}4.dll
                     DESTINATION ./
                     CONFIGURATIONS Release
                     COMPONENT Applications)
                 add_custom_target(${qtlib}-Debug-Copy ALL
                             COMMAND ${CMAKE_COMMAND} -E
copy_if_different ${QT_DLL_PATH_tmp}/${qtlib}${TYPE}4.dll
                             ${CMAKE_RUNTIME_OUTPUT_DIRECTORY}/Debug/
                             COMMENT "Copying ${qtlib}${TYPE}4.dll to $
{CMAKE_RUNTIME_OUTPUT_DIRECTORY}/Debug/")
                 add_custom_target(${qtlib}-Release-Copy ALL
                             COMMAND ${CMAKE_COMMAND} -E
copy_if_different ${QT_DLL_PATH_tmp}/${qtlib}4.dll
                             ${CMAKE_RUNTIME_OUTPUT_DIRECTORY}/Release/
                             COMMENT "Copying ${qtlib}4.dll to $
{CMAKE_RUNTIME_OUTPUT_DIRECTORY}/Release/")
               ENDIF (WIN32)
             ENDFOREACH(qtlib)

         endif()
     endif(DEFINED QT_QMAKE_EXECUTABLE)
endif()
