Subject: loader: fix duplicate detection of manifests when CMAKE_INSTALL_PREFIX is defined
X-Git-Tag: upstream/1.1.92~2253
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1fc9abd7d70166f72b44f7ea554ae80472003ed2;p=platform%2Fupstream%2FVulkan-Tools.git

loader: fix duplicate detection of manifests when CMAKE_INSTALL_PREFIX is defined

This commit fixes GH-1084. (see the issue for more details)

Note that this adds /usr/local/etc and /usr/local/share to the
loader's search path for drivers and layers.
