> When building the Arrow library _without_ using vcpkg on a Windows system that has vcpkg installed, msbuild emits this message repeatedly during the build:
> {quote}{{The vcpkg manifest was disabled, but we found a manifest file in $(VcpkgManifestRoot). You may want to enable vcpkg manifests in your properties page or pass /p:VcpkgEnableManifest=true to the msbuild invocation.}}
> {quote}
> This is of no consequence but it's annoying. See if we can configure the cmake files to add {{/p:VcpkgEnableManifest=false}} to the compiler flags to suppress this message when vcpkg is not being used for dependencies.
> E.g. in {{SetupCxxFlags.cmake}}, add a conditional like this, including a status message.
> {code:java}
> if(MSVC AND NOT ARROW_DEPENDENCY_SOURCE STREQUAL "VCPKG")
>   message(STATUS "Disabling the vcpkg manifest. To enable the vcpkg manifest, set -DARROW_DEPENDENCY_SOURCE=VCPKG")
>   set(CXX_COMMON_FLAGS "${CXX_COMMON_FLAGS} /p:VcpkgEnableManifest=false")
> endif(){code}
