[package] boost/1.76.0: namespace option results in missing libraries + ConanException

[Mortal42]

Using boost:namespace causes errors. Boost builds successfully but the recipe fails as it is looking for the default library names.
Was able to workaround by modifying add_libprefix in the recipe to replace "boost_" with str(self.options.namespace) + '_').

Package and Environment Details (include every applicable attribute)

• Package Name/Version: boost/1.76.0
• Operating System+version: Linux Ubuntu 20.04
• Compiler+version: GCC 10
• Docker image: conanio/gcc10
• Conan version: conan 1.36.0
• Python version: Python 3.7.5

Conan profile (output of conan profile show default or conan profile show <profile> if custom profile is in use)

Configuration for profile default:

[settings]
os=Linux
os_build=Linux
arch=x86_64
arch_build=x86_64

[env]

Steps to reproduce (Include if Applicable)

podman run -it --name conan conanio/gcc10 bash
conan install boost/1.76.0@ -o boost:namespace=my_boost -b missing
