You can try using a post-install script to copy the executable from one
install destination to the other:

# CMakeLists.txt:
ADD_EXECUTABLE(foo foo.cxx)
INSTALL_TARGETS(/bin1 foo)
CONFIGURE_FILE(${PROJECT_SOURCE_DIR}/post_install_foo.cmake.in
                ${PROJECT_BINARY_DIR}/post_install_foo.cmake
                @ONLY IMMEDIATE)
SET_TARGET_PROPERTIES(foo PROPERTIES
   POST_INSTALL_SCRIPT "${PROJECT_BINARY_DIR}/post_install_foo.cmake")

# post_install_foo.cmake.in:
EXEC_PROGRAM("@CMAKE_COMMAND@" ARGS -E copy
   "$ENV{DESTDIR}@CMAKE_INSTALL_PREFIX@/bin1/foo"
   "$ENV{DESTDIR}@CMAKE_INSTALL_PREFIX@/bin2/foo")
SET(CMAKE_INSTALL_MANIFEST_FILES ${CMAKE_INSTALL_MANIFEST_FILES}
   "@CMAKE_INSTALL_PREFIX@/bin2/foo")

The only part missing from this example is support for windows.  It is 
pretty easy to configure whether a .exe extension is included when 
copying the file, but I'm guessing you don't need this backward 
compatibility duplicate copy for windows because you said it came from 
an old make system.
