howto_build.txt

This directory include the libraries required by all x64 build of xptools.
Unlike the OSX/Linux libraries, which always have to be built be any developer
from source with a provided makefile - for windows its a less automated approach:
Some libraries require building with nmake on the command line, other have a 
msvc2017 *.sln ready to compile.

Either build method on windows requires a manual copy of the relevant include 
and output files into the into the respective ./include and ./lib directories. 
For his reason, the precompiled libraries and other files in these two 
directories are included in the git repository, so normally no action is 
required when compiling the XPtools with msvc2017.
