I have a library that is split up into 3 parts right now: a utilities lib, platform lib, and a renderer. I want them all the be their own separate .dll and .lib files. My issue is that I cannot seem to get VS to output all the files. My batch file looks like this:

@echo off
cls

set sable_dir=W:\dev\c\sable_lib
set src_dir=%sable_dir%\src
set deps_dir=%sable_dir%\deps

set macros=/DSABLE_LIB_EXPORT
set compiler_flags=/LDd /Zi
set linker_flags=/DLL /DEBUG

set sable_lib_libs=
set sable_lib_source_files=%src_dir%\sable_lib\sable_lib.c
set sable_lib_output=sable_lib.dll

set sable_platform_libs=sable_lib.lib %deps_dir%\sdl2\lib\x64\SDL2main.lib %deps_dir%\sdl2\lib\x64\SDL2.lib
set sable_platform_source_files=%src_dir%\sable_lib\sable_platform.c
set sable_platform_output=sable_platform.dll

set sable_renderer_libs=sable_lib.lib sable_platform.lib %deps_dir%\sdl2\lib\x64\SDL2main.lib %deps_dir%\sdl2\lib\x64\SDL2.lib %deps_dir%\sdl2\lib\x64\SDL2_image.lib
set sable_renderer_source_files=%src_dir%\sable_lib\sable_renderer.c %src_dir%\sable_lib\sera\sera.c
set sable_renderer_output=sable_renderer.dll

pushd W:\dev\c\sable_lib\bin

call "C:/Program Files (x86)/Microsoft Visual Studio 12.0/VC/vcvarsall.bat" x64

echo BUILDING SABLE_RENDERER
echo. 
cl %compiler_flags% /Fe%sable_renderer_output% %macros% %sable_renderer_source_files% %sable_renderer_libs% /link %linker_flags%

popd

When the first CL runs it outputs the sable_lib.lib file then sable_lib.dll, which is what I want. Then when cl runs again it outputs sable_platform.dll and sable_lib.lib not sable_platform.lib. Why is this? sable_renderer will not compile without sable_platform.lib. I'm compiling it using sublime text 3's build systems to run the batch file. This is the output:
