build

1. To build fds-client, you need to compile Poco(complete edition) & gtest manually.
2. After poco and gtest are built, you can use CMake to build the client itself:

   $ mkdir build
   $ cd build
   $ cmake .. -DPOCO_INCLUDE=/my/poco/include -DPOCO_LIB=/my/poco/lib -DGTEST_INCLUDE=/my/gtest/include -DGTEST_LIB=/my/gtest/lib
   $ make
