 You can generate the solution using CMake and build it using Visual Studio.
 
+Some of the utilities also depend on a few Boost libraries.
+In particular, Boost.ProgramOptions has to be built prior to building these utilities.
+To enable CMake to find Boost libraries, pass the path to the root Boost directory like this:
+
+    cmake -D BOOST_ROOT=C:\workspace\third-party\boost_1_58_0 ...
+
+Remember that in order to link to the static Boost libraries, you also have to pass `-D Boost_USE_STATIC_LIBS=ON` to CMake.

 ## Running on older CPUs
 
 To run programs that are using the AES-NI instruction set on a CPU w/o the support for these instructions, one can use
 [Intel Software Development Emulator](https://software.intel.com/en-us/articles/intel-software-development-emulator).
 You can then run a program like this:
 
-    > sde -- aes128ecb_encrypt_block.exe 000102030405060708090a0b0c0d0e0f 00112233445566778899aabbccddeeff
+    > sde -- encrypt_block_aes.exe -a aes128 -m ecb -- 000102030405060708090a0b0c0d0e0f 00112233445566778899aabbccddeeff
