[package] paho-mqtt-cpp/1.2.0: shared library builds unnecessarily forbidden on Windows

Description

The paho-mqtt-cpp/1.2.0 recipe explicitly forbids option shared=True on Windows. However, it shouldn't be forbidden because shared library creation works fine on Windows. I have verified that with MSVC 19.16 (Visual Studio 2017) and MSVC 19.24 (Visual Studio 2019).

Package and Environment Details

Package Name/Version: paho-mqtt-cpp/1.2.0
Operating System+version: Windows 10
Compiler+version: MSVC 19.16 (Visual Studio 2017) / MSVC 19.24 (Visual Studio 2019)
Conan version: conan 1.42.2

Conan profile

MSVC 19.16:

arch=x86_64

Steps to reproduce

Apply the following patch to the paho-mqtt-cpp recipe:


--- a/recipes/paho-mqtt-cpp/all/conanfile.py
+++ b/recipes/paho-mqtt-cpp/all/conanfile.py
@@ -37,9 +37,6 @@ class PahoMqttCppConan(ConanFile):
     if self.settings.compiler.cppstd:
         tools.check_min_cppstd(self, minimal_cpp_standard)

if self.settings.os == "Windows" and self.options.shared:
raise ConanInvalidConfiguration("{} can not be built as shared on Windows.".format(self.name))

 self.options["paho-mqtt-c"].shared = self.options.shared
 self.options["paho-mqtt-c"].ssl = self.options.ssl


2. Build packages using MSVC / Visual Studio compiler and `shared=True`.
3. See that it works fine.
