How to add vdi support to qemu-img?

Take qemu fairly new, with vdi support (it's been there for > 10 years, this part shouldn't cause problems). Configure it with the key --enable-vdi. Build. Something like that:

$ wget https://download.qemu.org/qemu-5.2.0.tar.xz
$ tar -xf qemu-5.2.0.tar.xz
$ mkdir build
$ cd build
$ ../qemu-5.2.0/configure --prefix=`pwd`/root --enable-vdi --enable-tools --disable-user --disable-system
$ make && make install
$ root/bin/qemu-img --help | grep vdi
Supported formats: blkdebug blklogwrites blkverify bochs cloop compress copy-on-read dmg file ftp ftps host_cdrom host_device http https luks nbd null-aio null-co nvme parallels qcow qcow2 qed quorum raw replication throttle vdi vhdx vmdk vpc vvfat
