#! /usr/bin/env wish BUILD

# This CMake script has some complications to consider:
#
#   -DARCH=32          Architecture bits to use non-MSVC targets 
#   -DARCH=64          (GCC/Clang/etc) that take the -m32 and -m64 flags.
#                      (For MSVC targets, select the correct -G option.)
#
#   -DLINKAGE=direct   Compile csprng.c/cpp directly into the exe
#   -DLINKAGE=static   Build libcsprng.a/csprng.lib and link that with exe
#
# The BUILD script is designed to handle these considerations for you.
