Description of problem:
I have found et package provides bundled(cpp-httplib). Please try to use cpp-httplib-devel shared package instead of internal copy of library.

Version-Release number of selected component (if applicable):
et-0:6.2.1-2.fc36.x86_64

How reproducible:
reliable

Steps to Reproduce:
1. dnf repoquery --whatprovides 'bundled(cpp-httplib)'
2.
3.

Actual results:
et-0:6.1.11-2.fc36.x86_64
et-0:6.2.1-2.fc36.x86_64

Expected results:
empty

Additional info:
the library has not small testsuite, which makes sure the library is working. Fedora packages should use tested version if possible.
