Can't tell cmake to use vcpkg for library link

Question

I'm using a Cmake for a cross-platform project that use glibmm. Under Linux, the project build successfully without any problem (and works fine when executed).

But with Windows 10, Visual Studio 2019 (pro), I can't find how to build the project. I installed glibmm with vcpkg ("vcpkg install glibmm:x64-windows" and "vcpkg install glibmm:x86-windows")

I add to my cmake command the parameter -DCMAKE_TOOLCHAIN_FILE=D:\vcpkg\scripts\buildsystems\vcpkg.cmake

In the main CMakeLists.txt file, the following lines do not do their job.

find_package(PkgConfig REQUIRED)
pkg_check_modules(glibmm REQUIRED glibmm-2.4)

cmake -S D:\MachDrivetoolkit\libMachDrive -DCMAKE_TOOLCHAIN_FILE=D:\vcpkg\scripts\buildsystems\vcpkg.cmake -DPKG_CONFIG_EXECUTABLE:STRING="D:\vcpkg\downloads\tools\msys2\c809757c94447846\mingw32\bin\pkg-config.exe" -B D:\MachDrivetoolkit\libMachDriveVS

  libipc/CMakeLists.txt:37 (pkg_check_modules)

Then I modify the name of the glibmm library in the script to match the name of the installed file

find_package(PkgConfig REQUIRED)
pkg_check_modules(glibmm REQUIRED glibmm)

but it fail the same.

What parameters or what instruction should I use to link glibmm to my project ?
