I think you need to do a make clean.

And I found why I didn't catch that problem.  Fedora pkg-config is soooo
intelligent:

$ pkg-config --exist libzstd; echo $?
0
$ pkg-config --exists libzstd; echo $?
0
$ pkg-config --exists libzstd33; echo $?
1
$ pkg-config --exist libzstd33; echo $?
1
$ 

I tried with libzstd-devel installed and uninstalled, with --enable-zstd
and --disable-zstd, and it always did the right thing for me.

Later, Juan.
