# Note: (Windows + vcpkg) to build and use x64:
# a) set VCPKG_DEFAULT_TRIPLET=x64-windows, then install all required dependencies
# b) invoke cmake for 64 bit platform, as follows:
#    cmake -DCMAKE_GENERATOR_PLATFORM=x64 ..
# or, i.e.: 
#    cmake -G "Visual Studio 15 2017 Win64" ..
# This assumes CMAKE_TOOLCHAIN_FILE is correctly set, in accordance with
# https://github.com/Microsoft/vcpkg/blob/master/docs/examples/using-sqlite.md#cmake
