openssl: cannot find perl

[TheClonerx]

despite openssl requiring perl in order to build, it is not specified in the recipe's tool_requirements.
while some distribution (such as debian & archlinux) do provide perl while installing cmake, gcc, and make, others such as fedora don't.
the docs mention that only cmake is assumed to be installed: https://github.com/conan-io/conan-center-index/blob/master/docs/adding_packages/dependencies.md#build-requirements

to reproduce:

podman run --rm -it fedora
dnf install gcc g++ cmake conan
conan profile detect
# might need to add gcc 14 to ~/.conan2/settings.yml
conan install --requires "openssl/[*]" -b missing

# ...

of course could be easily solved by just installing perl through the system package manager, but in some situations one does not have root access to do such thing.

Indeed, but there is no perl recipe in conan-center (only strawberryperl recipe for Windows). One could create such recipe. Source code of 5.38.2: https://www.cpan.org/src/5.0/perl-5.38.2.tar.gz
