REM Synthesise vulkan-1.lib from the system vulkan-1.dll.
|
||||
REM
|
||||
REM This removes the need to install the LunarG Vulkan SDK (~1 GB) just to get
|
||||
REM an import library: Windows already ships vulkan-1.dll, and we only need the
|
||||
REM matching .lib so the MSVC linker can resolve vkCreateInstance & friends.
|
||||
REM
|
||||
REM Run from a *plain* cmd/PowerShell: this script sets up the MSVC environment
|
||||
REM itself via vcvars64.bat.
|
||||
REM
|
||||
REM NOTE: deliberately avoids parenthesised if-blocks and avoids
|
||||
REM `setlocal EnableDelayedExpansion`, because this script's own paths contain
|
||||
REM "(x86)" -- expanding such a value inside a ( ) block truncates the block
|
||||
REM and yields "\Microsoft was unexpected at this time."
