[Bug 1916655] [NEW] Compilation fails due to zstd qcow2 compression |

Public bug reported:
Compilation of QEMU fails when using recent versions of zstd.
I use the following commands to compile QEMU:
$ mkdir build
$ cd build
$ ../configure --enable-debug --target-list=x86_64-softmmu
$ make -j $(nproc)
Here is a paste from the ../configure output:
https://paste.ubuntu.com/p/dHsWzGV7TH/
And one from the make output:
https://paste.ubuntu.com/p/89qKk4NrFz/
In short the error boils down to:
../block/qcow2-threads.c: In function ‘qcow2_zstd_compress’:
../block/qcow2-threads.c:225:16: error: implicit declaration of function
‘ZSTD_compressStream2’; did you mean ‘ZSTD_compressStream’?
[-Werror=implicit-function-declaration]
225 | zstd_ret = ZSTD_compressStream2(cctx, &output, &input, ZSTD_e_end);
| ^~~~~~~~~~~~~~~~~~~~
| ZSTD_compressStream
../block/qcow2-threads.c:225:16: error: nested extern declaration of
‘ZSTD_compressStream2’ [-Werror=nested-externs]
../block/qcow2-threads.c:225:60: error: ‘ZSTD_e_end’ undeclared (first use in
this function)
225 | zstd_ret = ZSTD_compressStream2(cctx, &output, &input, ZSTD_e_end);
