CMake FetchContent not building OpenMPI library in Visual Studio

I'm trying to add openmpi as a static library to my c++ project on a Windows Visual Studio environment using the mscv compiler. However, the FetchContent_MakeAvailable command does not seem to be building the library from the dowloaded source.

My CMakeLists.txt

cmake_minimum_required(VERSION 3.18)
project(test)

include(FetchContent)

set(FETCHCONTENT_QUIET FALSE)

 FetchContent_Declare(
    openmpi
    GIT_REPOSITORY https://github.com/open-mpi/ompi.git
    GIT_TAG v2.0.0
 )

 FetchContent_MakeAvailable(openmpi)

add_executable(test main.cpp)

target_link_libraries(
    test
    openmpi
)

Output

In the build/x64-Debug/_deps folder the subfolders openmpi-src and openmpi-subbuild are populated but openmpi-build is empty with no library files to link to.
