[question] No such file or directory in sub-dependency

[Womps]

What is your question?

Hello,

I'm trying to use net-snmp in my Windows C++ project with conan. I only want to consume this package. In the documentation, it is recommended to use a conanfile.txt for this.

I'm using the Conan version 2.23.0 and my default profile looks like this :

[settings]
arch=x86_64
build_type=Debug
compiler=msvc
compiler.cppstd=14
compiler.runtime=dynamic
compiler.version=194
os=Windows

My CMakeLists.txt looks like this :

cmake_minimum_required(VERSION 3.28)
project (MyApp LANGUAGES CXX)

set(CMAKE_CXX_STANDARD 14)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

find_package(net-snmp REQUIRED CONFIG)

add_executable (MyApp
    src/main.cpp
    src/mib/MibManager.cpp
    src/mib/MibManager.h)

target_include_directories(MyApp PRIVATE src)

target_link_libraries(MyApp PRIVATE
    net-snmp::net-snmp
)

I install dependencies of my project using :

mkdir build && cd build
conan install ../ --build=missing

In my code, I'm including net-snmp headers using :

extern "C"
{
    #include <net-snmp/net-snmp-config.h>
    #include <net-snmp/net-snmp-includes.h>
}

When I try to build, either using my VS (using -DCMAKE_TOOLCHAIN_FILE), or via cmake directly in a command prompt, I get the following error :
C:\$HOME\.conan2\p\b\net-s5034841eeb4fb\p\include\net-snmp\library\scapi.h(14,10): error C1083: Cannot open included file : 'openssl/ossl_typ.h' : No such file or directory

I dont need openssl in my app, currently. Only net-snmp uses it in its dependencies. It looks like the toolchain does not set the include dirs or something like that. Can someone explain me what am I doing wrong here, please ?

Have you read the CONTRIBUTING guide?

Hi @Womps thanks a lot for taking the time to report this, we appreciate it.

In fact, this would not be a client issue, but an issue specific to the recipe for this library.

I've now proposed #29237 to fix this issue.

Once merged, recall to run your conan install command with the --update flag so that Conan picks up the new revision of the recipe, which should fix the issues you're seeing :)

Thanks for your help ! I was not sure if it was normal or a wrong usage, so it took me some time before posting here ;)

Thanks again, I'll wait for the fix !

#29237 has been merged, you can try again now, thanks!
