Release jpeg62.dll copied to debug build directory

[tksharpless]

Describe the bug
building a project with VS22 with vcpkg integration (legacy mode), the jpeg62.dll copied to debug build directory is in fact the release version. I know this because in debug, OpenCV passes debug parameters to jpeg read that the release jpeg code does not recognize, so it throws an exception. Moreover the dll in question is much smaller than the correct debug one, and binary identical to the one vcpkg copies for the release build.

I suppose this has something to do with the fact that the jpeg package uses the same file name for both dlls -- and that might be a port bug.

Environment

• OS: Win11
• Compiler: VS22
  The vcpkg directories 'installed\x64-windows\bin' and 'installed\x64-windows\debug\bin' respectively contain the correct release and debug jpeg62 dlls.

To Reproduce
Steps to reproduce the behavior:

1. run the debug build. happens every time.

Expected behavior
The right jpeg dll should be copied.

I tried to debug this from 'diagnostic' build output and logs after a full rebuild. There are zillions of records in numerous log files that show where jpeg62.dll was written to, but I can find none showing explicitly where it was read from. In all that massive output there are just two mentions of the name of the expected vcpkg installed bin directory, both in this extract from the build log. I would read this as showing jpeg62.dll and several others being copied from D:\opensource\vcpkg\installed\x64-windows\debug\bin, as they should be. And that is exactly what happened: after this rebuild, the right jpeg dll was there. And it was still there after an incremental build.
So I am beginning to suspect a Cmake problem.

I would naively assume that this shows libjpeg62 being copied from debug\bin along with all the other (correct) debug dlls

It is a Cmake problem, and maybe also a Visual Studio fault. Changing cmakelists.txt triggered a build that replaced all the debug dlls with release ones, because cmake generated a VS project in which the Vcpkg Configuration for the debug build was incorrectly set to Release. I have seen this fault on several cmake/vcpkg projects.
After changing that setting to Debug, an incremental build replaced all the dlls with debug ones, EXCEPT jpeg62.dll. And this despite the fact that jpeg62.pdb appeared alongside it.
Finally, a full rebuild installed the correct jpeg62.dll. So there is a workaround, but I'd like to get this anomaly patched if possible.

Apart from cmake caching effects in your project, complex packages like vtk sometimes trigger rare cases of picking some link libs or link directories from the wrong build type. This eventually leads to the wrong DLL being deployed.
