Subject: meson: wasapi2,mediafoundation: Work around Windows SDK header issue
X-Git-Tag: 1.19.3~182
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=47a53f50637965919447f721b3956b974a2a0afd;p=platform%2Fupstream%2Fgstreamer.git

meson: wasapi2,mediafoundation: Work around Windows SDK header issue

Some SDK headers are not standard compliant, so MSVC will
complain when such headers are in use with "/permissive-" compile
option. Use "/Zc:twoPhase-" to work around the issue as documented in
https://docs.microsoft.com/en-us/cpp/build/reference/permissive-standards-conformance?view=msvc-160#windows-header-issues
