While running cmake 3.21.1 (shipped with Qt online installer) on same project on macOS and Windows I get different output. Why? And how to make it more verbose on Windows?

CMakeLists.txt

cmake_minimum_required(VERSION 3.19.1)

set(CMAKE_TOOLCHAIN_FILE ~/vcpkg/scripts/buildsystems/vcpkg.cmake)

project(MYLIB)

set (CMAKE_CXX_STANDARD 14)

find_package(OpenCV REQUIRED)

include_directories(~/vcpkg/installed/x64-osx/include)

link_libraries(${OpenCV_LIBS})

set(CMAKE_WINDOWS_EXPORT_ALL_SYMBOLS TRUE)

add_library(mylib SHARED mylib.cpp another_lib.cpp)
