make install

输出信息（最后）：
Libraries have been installed in:
/usr/local/lib/../lib64

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:

• add LIBDIR to the `LD_LIBRARY_PATH' environment variable
  during execution
• add LIBDIR to the `LD_RUN_PATH' environment variable
  during linking
• use the `-Wl,-rpath -Wl,LIBDIR' linker flag
• have your system administrator add LIBDIR to `/etc/ld.so.conf'
