correct platforms. ceph currently doesn't build on aarch64-linux. So
let's not lie in meta.platforms.
ceph: fix multiple output
We currently just move $out/share/ceph/mgr to
$lib/lib/ceph, and then remove all references to $out with a find
command.
I checked $out, the only reference to $out is in
$lib/lib/ceph/libceph-common.so.0, coming from src/common/options.cc:
https://github.com/ceph/ceph/blob/master/src/common/options.cc#L5050:
> Option("mgr_module_path", Option::TYPE_STR, Option::LEVEL_ADVANCED)
> .set_default(CEPH_DATADIR "/mgr")
> .add_service("mgr")
> .set_description("Filesystem path to manager modules."),
Just removing the reference might break some behaviour - it should point
to $lib/ceph/mgr instead.
We can fix this in a much more elegant fashion by just passing a custom
CMAKE_INSTALL_DATADIR to the build system.
ceph: fix outdated Boost::python substitutions
Instead of substituting in CMakeLists.txt files, one now needs to set
MGR_PYTHON_VERSION.
ceph: clean up PYTHONPATH wrapping
Set `pythonPath` instead of exporting PYTHONPATH.
Use `toPythonPath` to construct the PYTHONPATH where we need manual
wrapping. There's no ceph-volume, only ceph-mgr.
ceph: set doCheck = false explicitly
and describe why.
ceph: patch more shebangs
ceph: use system-provided gtest and rocksdb
This is required for programs using rocksdb and and typeinfo.
Otherwise, linking them fails with errors like this (that's ceph):

I think those deps could be made to build, but I didn't want to get
bogged down investigating further. "Use flags" are always a good thing,
so this is fine for now.
