DLLs managed by vcpkg get removed from output dir when only custom build steps are triggered (MSVC) #23183

Open jjYBdx4IL opened 2 years ago

jjYBdx4IL commented 2 years ago

I'm using https://www.reedbeta.com/blog/custom-toolchain-with-msbuild/ as a template to convert markdown files to rtf and html in my MSVC c++ project.

Everything works fine -- until I make only changes to a markdown file. Then the custom build steps get executed, but the DLLs copied by vcpkg are suddenly gone from the output directory. It looks as if vcpkg sees that a build has been run, decided that the (new) output didn't contain anything needing the DLLs, and then removes them at the end of the build.

Any ideas how to fix that?

Here are the relevant modifications:

.vcxproj:

  <Import Project="targets.xml" />

        <!--<AdditionalInputs>$(ShaderHeaders)</AdditionalInputs>-->

Which port are you installed? Could you please provide your demo repro project to me?

jjYBdx4IL commented 2 years ago

vcpkg integrate install vcpkg install wxwidgets:x64-windows boost-algorithm:x64-windows

https://github.com/jjYBdx4IL/vcpkg-issue-23183-demo

Latest public Visual Studio 2019 release on Windows 11/x64.

Boost isn't needed with this demo, though.
