IIRC these are not public API so no reason to install it.

Why not? Need them, works fine while using git, but with vcpkg these folders are missing.

[kcrif]

Need NFile, NDir, IInArchive, CPropVariant etc.

[Osyotr]

Please share your usage.
NFile::/NDir::/CPropVariant are not exported from the DLL.

[kcrif]

Have some code based on

https://github.com/ip7z/7zip/blob/main/CPP/7zip/UI/Client7z/Client7z.cpp

within this code all these files are needed

[Osyotr]

Again, this API is not exported from the DLL, so you will get linker errors if you attempt to use it.

Please try to build the provide example [Client7z] from the git folder that also comes with the download from https://7-zip.org/a/7z2301.msi. Works like a charm. Trying to use this example with vspkg the build fails. For what reason i should not be able to build the provided examples? Even why is the example not part of the Package?
