The package msgpack:x64-linux provides CMake targets:

    find_package(msgpack CONFIG REQUIRED)
    target_link_libraries(main PRIVATE msgpackc msgpackc-cxx msgpackc-static)

Configure the project with a minimal CMakeLists.txt:

cmake_minimum_required(VERSION 3.10)

project(test-mp)

find_package(msgpack CONFIG REQUIRED)

add_executable(test-mp main.cpp)

target_link_libraries(test-mp PRIVATE msgpackc msgpackc-cxx msgpackc-static)

using the toolchain

$ cmake -DCMAKE_TOOLCHAIN_FILE=~/b/vcpkg/scripts/buildsystems/vcpkg.cmake ..

CMake Error at /home/hg/b/vcpkg/scripts/buildsystems/vcpkg.cmake:198 (_add_library):
  _add_library cannot create ALIAS target "msgpackc" because target
  "msgpackc-static" is imported but not globally visible.

I could use all other required packages from vcpkg but msgpack.

CMake Version: 3.13.2

$ cmake -DCMAKE_TOOLCHAIN_FILE=~/b/vcpkg/scripts/buildsystems/vcpkg.cmake ..

triplet?

It also happened to me.

I tried to update to tag cpp-3.2.0 and skip the patches but the error was the same.

I'm also having this problem with a fresh checkout of tags/cpp-3.2.0

Same Here

commit 2e7f3f6f48a3d4d3c21f0faacbc2c9efbbe700d0 (HEAD -> master, origin/master, origin/HEAD)

[giellamoswhard]

I've temporarly got around this by adding GLOBAL to the the line
add_library(msgpackc-static STATIC IMPORTED GLOBAL)

in the file vcpkg/installed/x64-linux/share/msgpack/msgpack-targets.cmake
