How to debug vcpkg.exe integrate install?

[patrikhuber]

Hi,

I've had it a few times now that I create a new C++ project in VS (no CMake, just a plain VS C++ console app) but including stuff from vcpkg doesn't work. Like just now, #include <Eigen/Core> - fatal error C1083: Cannot open include file: 'Eigen/Core': No such file or directory. I've re-run vcpkg.exe integrate install and re-opened the VS solution, but no use.
And I can confirm the files are present in C:\Users\Patrik\vcpkg\installed\x64-windows\include\Eigen.

What can I do to debug/fix this?

Thanks for posting this issue!

In Tools -> Options -> Projects and Solutions -> Build and Run, there are settings for the "MSBuild project build output verbosity". If you increase this to at least "Normal", you will see a message like:

Using triplet "x64-windows" from "D:\src\vcpkg\installed\x64-windows\"

If you increase it to "Detailed", you'll see the command lines used to compile which should include the include directive (something like /I"D:\src\vcpkg\installed\x64-windows\include")

I am having the same issue, admittedly it is with visual studio 2019, v16.2.2.
Have some MSBuild paths changed in this release?
If I know what's changed, I'm happy to submit a PR as I have some time and need this to work for other projects.
