x64-windows-static

Add the following lines to CMakeLists.txt before find_package:

string(REGEX REPLACE "/MD" "/MT" CMAKE_CXX_FLAGS ${CMAKE_CXX_FLAGS})
string(REGEX REPLACE "/MD" "/MT" CMAKE_CXX_FLAGS_DEBUG ${CMAKE_CXX_FLAGS_DEBUG})
string(REGEX REPLACE "/MD" "/MT" CMAKE_CXX_FLAGS_RELEASE ${CMAKE_CXX_FLAGS_RELEASE})

(I tried cmake_policy(SET CMP0091 NEW) and set(CMAKE_MSVC_RUNTIME_LIBRARY "MultiThreaded$<$<CONFIG:Debug>:Debug>") but it does not work)

Linux or macOS

Default (statically linked):

cmake -B build
cmake --build build
./build/HelloWorld

Dynamically linked:

cmake -B build-dynamic -DVCPKG_TARGET_TRIPLET=<triplet>
cmake --build build-dynamic
./build/HelloWorld

The triplet could be one of the following according to the architecture and OS:

• arm64-osx-dynamic
• x64-osx-dynamic
• x64-linux-dynamic

See the supported triplet in https://github.com/microsoft/vcpkg/tree/master/triplets
