ogg.m4 not installed when built using cmake #99
Description
Working on openSUSE TUmbleweed (rolling distro)
I was chasing an error in a dependent package (celt, quite outdated, but well) that no longer built after the latest upgrade in our package, which happened to switch to cmake as the build system of choice (used configure/make/make install before)
turns out the issue is that celt relies on ogg.m4 (for autoreconf), but ogg being built using cmake omits this file from being installed
