LIBXML2 not found

[ghost]

I solved Python detection, but I cannot solve problem with libxml2

[marcelolr]

Can you provide more information on the libxml2 problem? What steps are you taking and what errors are you seeing?

I tried install clear Windows, Visual Studio 2017, cmake, python, and build by hctbuild. Sorry, forgot to give log. Before been given another (with not founded python).

Default architecture - set BUILD_ARCH=x64

You can recreate the environment with this command.

Setting up macros for this console - run hcthelp for a reference.

Got it. The problem isn't with libxml2, we don't really need that to build. The problem is with missing TAEF files, which we use for building and running tests. The root README.md has a little blurb on this.

Tests are built using the TAEF framework. Unless you have the Windows Driver Kit installed, you should run the script at utils\hct\hctgettaef.py from your build environment before you start building to download and unzip it as an external dependency. You should only need to do this once.

Please let us know if you run into any other build issues of this sort - thanks!
