build error: "/usr/bin/ld: cannot find -lstdc++fs: No such file or directory"

I am trying to build an RPM for ET in Photon 5.0, but I am running into this error:

[ 84%] Linking CXX executable htm

I have the following build requires in the spec file:

BuildRequires:  boost-devel
BuildRequires:  cmake
BuildRequires:  gflags-devel
BuildRequires:  curl-devel
BuildRequires:  libsodium-devel
BuildRequires:  libstdc++-devel
BuildRequires:  libutempter-devel
BuildRequires:  ncurses-devel
BuildRequires:  openssl-devel
BuildRequires:  protobuf-devel
BuildRequires:  protobuf-c-static
BuildRequires:  protobuf-c-devel
BuildRequires:  systemd
BuildRequires:  zlib-devel

But it looks like there is something missing. I found this though with Google: https://stackoverflow.com/questions/74891427/make-error-library-not-found-for-lstdcfs , indicating it should actually not be necessary. Our version of libstdc++ is 12.2.0:

root [ ~ ]# tdnf info libstdc++-devel
Name          : libstdc++-devel
Arch          : x86_64
Epoch         : 0
Version       : 12.2.0
Release       : 1.ph5
...

I could fix this by removing stdc++fs from CMakeLists.txt:

diff --git a/CMakeLists.txt b/CMakeLists.txt
index 47320878..39730bac 100644
--- a/CMakeLists.txt
+++ b/CMakeLists.txt
@@ -274,7 +274,7 @@ else()
       util
       resolv
       atomic
-      stdc++fs)
+      )
 endif()
 
 IF(Unwind_FOUND)

A proper fix should probably involve checking for the libstdc++ version.

Issue still exists in 6.2.8.
