#if !defined(GLFW_INCLUDE_NONE)
 #define GLFW_INCLUDE_NONE
#endif

Solution:
Turn off DUSE_MSVC_RUNTIME_LIBRARY_DLL when building with cmake.
cmake command:

cmake -DBUILD_SHARED_LIBS=OFF -DGLFW_BUILD_EXAMPLES=OFF -DGLFW_BUILD_TESTS=OFF -DGLFW_BUILD_DOCS=OFF -DUSE_MSVC_RUNTIME_LIBRARY_DLL=OFF -G "Visual Studio 16 2019" -A x64
MSBuild GLFW.sln /p:Configuration=Release /p:Platform=x64

Solution:
Add dependency of User32 in build.zig:

exe.addLibPath("D:/Program_Filesx86/Windows Kits/10/Lib/10.0.18362.0/um/x64");
exe.linkSystemLibrary("User32");
