Having this is as simple as:

add_library( mysharedlib SHARED ${LIB_SRCS} )

add_executable( mycliapp ${CLI_SRCS} )
target_link_libraries( mycliapp mysharedlib )

add_executable( myguiapp ${CLI_SRCS})
target_link_libraries( myguiapp mysharedlib )

# This installs the library to CMAKE_INSTALL_PREFIX/lib and the
binaries to CMAKE_INSTALL_PREFIX/bin on *nix, see the cmake manual for
more details
install( TARGETS mysharedlib mycliapp myguiapp
           LIBRARY DESTINATION lib/
           RUNTIME DESTINATION bin/
         )

On Unix you might want to look into the RPATH options offered by
cmake, so your executables can easily find the shared library when its
installed in the users home directory or so, but under the same
base-directory.
