If no HAVE_STD_SHARED_PTR or HAVE_BOOST_SHARED_PTR then set ptr_lib to ndnboost in the boost headers in this distribution.

+// Use this file to define a site and compiler specific
+// configuration policy:
+//
+
+// define this to locate a compiler config file:
+// #define BOOST_COMPILER_CONFIG <myheader>
+
+// define this to locate a stdlib config file:
+// #define BOOST_STDLIB_CONFIG <myheader>
+
+// define this to locate a platform config file:
+// #define BOOST_PLATFORM_CONFIG <myheader>
+
+// define this to disable compiler config,
+// use if your compiler config has nothing to set:
+// #define BOOST_NO_COMPILER_CONFIG
+
+// define this to disable stdlib config,
+// use if your stdlib config has nothing to set:
+// #define BOOST_NO_STDLIB_CONFIG
+
+// define this to disable platform config,
+// use if your platform config has nothing to set:
+// #define BOOST_NO_PLATFORM_CONFIG
+
+// define this to disable all config options,
+// excluding the user config. Use if your
+// setup is fully ISO compliant, and has no
+// useful extensions, or for autoconf generated
+// setups:
+// #define BOOST_NO_CONFIG
+
+// define this to make the config "optimistic"
+// about unknown compiler versions. Normally
+// unknown compiler versions are assumed to have
+// all the defects of the last known version, however
+// setting this flag, causes the config to assume
+// that unknown compiler versions are fully conformant
+// with the standard:
+// #define BOOST_STRICT_CONFIG
+
+// define this to cause the config to halt compilation
+// with an #error if it encounters anything unknown --
+// either an unknown compiler version or an unknown
+// compiler/platform/library:
+// #define BOOST_ASSERT_CONFIG
+
+
+// define if you want to disable threading support, even
+// when available:
+// #define BOOST_DISABLE_THREADS
+
+// define when you want to disable Win32 specific features
+// even when available:
+// #define BOOST_DISABLE_WIN32
+
+// BOOST_DISABLE_ABI_HEADERS: Stops boost headers from including any
+// prefix/suffix headers that normally control things like struct
+// packing and alignment.
+// #define BOOST_DISABLE_ABI_HEADERS
+
+// BOOST_ABI_PREFIX: A prefix header to include in place of whatever
+// boost.config would normally select, any replacement should set up
+// struct packing and alignment options as required.
+// #define BOOST_ABI_PREFIX my-header-name
+
+// BOOST_ABI_SUFFIX: A suffix header to include in place of whatever
+// boost.config would normally select, any replacement should undo
+// the effects of the prefix header.
+// #define BOOST_ABI_SUFFIX my-header-name
+
+// BOOST_ALL_DYN_LINK: Forces all libraries that have separate source,
+// to be linked as dll's rather than static libraries on Microsoft Windows
+// (this macro is used to turn on __declspec(dllimport) modifiers, so that
+// the compiler knows which symbols to look for in a dll rather than in a
+// static library). Note that there may be some libraries that can only
+// be statically linked (Boost.Test for example) and others which may only
+// be dynamically linked (Boost.Threads for example), in these cases this
+// macro has no effect.
+// #define BOOST_ALL_DYN_LINK
+
+// BOOST_WHATEVER_DYN_LINK: Forces library "whatever" to be linked as a dll
+// rather than a static library on Microsoft Windows: replace the WHATEVER
+// part of the macro name with the name of the library that you want to
+// dynamically link to, for example use BOOST_DATE_TIME_DYN_LINK or
+// BOOST_REGEX_DYN_LINK etc (this macro is used to turn on __declspec(dllimport)
+// modifiers, so that the compiler knows which symbols to look for in a dll
+// rather than in a static library).
+// Note that there may be some libraries that can only be statically linked
+// (Boost.Test for example) and others which may only be dynamically linked
+// (Boost.Threads for example), in these cases this macro is unsupported.
+// #define BOOST_WHATEVER_DYN_LINK
+
+// BOOST_ALL_NO_LIB: Tells the config system not to automatically select
+// which libraries to link against.
+// Normally if a compiler supports #pragma lib, then the correct library
+// build variant will be automatically selected and linked against,
+// simply by the act of including one of that library's headers.
+// This macro turns that feature off.
+// #define BOOST_ALL_NO_LIB
+
+// BOOST_WHATEVER_NO_LIB: Tells the config system not to automatically
+// select which library to link against for library "whatever",
+// replace WHATEVER in the macro name with the name of the library;
+// for example BOOST_DATE_TIME_NO_LIB or BOOST_REGEX_NO_LIB.
+// Normally if a compiler supports #pragma lib, then the correct library
+// build variant will be automatically selected and linked against, simply
+// by the act of including one of that library's headers. This macro turns
+// that feature off.
+// #define BOOST_WHATEVER_NO_LIB
