We would like to allow parallel WPE installations which have different API versions. In order to allow this, we would need/want to install binaries (“WPEWebProcess”, “WPENetworkProcess”, and so on) into a versioned subdirectory of the libexec directory. For example the default could be “<prefix>/libexec/wpe-0.1”. Of course we also want to allow packagers to override the location if they deem it necessary.
I have a WIP patch for this already which I need to test before uploading it.
