I’m trying to build my project on macOS. I’m installing pre-reqs using vcpkg.

I’m getting this error:

```auto
1> [CMake] CMake Error at out/build/vcpkg_installed/arm64-osx/share/exiv2/exiv2Export.cmake:60 (set_target_properties):
1> [CMake] The link interface of target "Exiv2::exiv2lib" contains:
1> [CMake] 
1> [CMake] Iconv::Iconv
1> [CMake] 
1> [CMake] but the target was not found.

```

This rather puzzles me as I thought that iconv was shipped with macOS?

What do I need to do to fix this. I don’t use either macports or brew.

I’m using Cmake 3.31.4.

It appears that all I needed was:

```auto
if (${CMAKE_SYSTEM_NAME} STREQUAL "Darwin")
find_package(Iconv REQUIRED)
endif()

```

Or the original maintainer (_or vcpkg port author_) should have added [find\_dependency()](https://cmake.org/cmake/help/latest/module/CMakeFindDependencyMacro.html) to that library’s CMake config. That would be a preferred way, but unfortunately it is rather common that they don’t bother/care/aware.
