Profile
If you are using GCC compiler >= 5.1, Conan will set the compiler.libcxx to the old ABI for backwards compatibility. In the context of this getting started example, this is a bad choice though: Recent gcc versions will compile the example by default with the new ABI and linking will fail without further customization of your cmake configuration. You can avoid this with the following commands:
# generates default profile
conan profile new default --detect
# sets libcxx to C++11 ABI
conan profile update settings.compiler.libcxx=libstdc++11 default
conan profile remove settings.compiler.libcxx default
cat ~/.conan/profiles/default
ls -la ~/.conan/profiles/
Getting Started
cmake_minimum_required(VERSION 3.19)
Example: 1
cd $ACADEMIA_HOME/wss/ccpp_wss/
git clone https://github.com/conan-io/examples.git
cd examples/libraries/poco/md5/
conan search poco --remote=conancenter
conan inspect poco/1.9.4
cat conanfile.txt

conan install .. -s compiler="Visual Studio" -s compiler.runtime=MDd -s build_type=Debug -s compiler.version=16

mkdir ../build; cd ../build
conan install ..
