Subject: Don't export Vulkan functions when building the loader statically
X-Git-Tag: upstream/1.3.268~175
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=823209c89e86d7b9dd7becb7085aa9cd9a34961c;p=platform%2Fupstream%2FVulkan-Loader.git

Don't export Vulkan functions when building the loader statically

If the loader is linked statically, there is no need to export all
vulkan functions from the linking application. This issue showed up
in ANGLE which would export all GLES and Vulkan functions on Mac.
