Resolve "EXTERN: Adapt to Conan 2"

Summary

Updating from Conan 1 to Conan 2.5 required several changes, both on the conanfile.py as well as the CMakeLists.txt file(s).

Related to

• #73 (closed)
• #80 (closed)
• #82 (closed)
• #83 (closed)

Related MR for integration tests: caosdb-cppinttest!35 (merged)

Focus

The biggest changes are in conanfile.py and CMakeLists.txt all according to the migration guide. Crucial here are

• Conan now doesn't appear in the CMakeLists.txt files anymore. Instead, Conan generates CMakeToolChain files, which handle all the necessary includes etc. The toolchain files are passed to CMake as arguments.
• Packages are included in our CMakeLists.txt using CMake's FindPackage
• Conan 2.0 builds into build/<build_type>, i.e. build/Release or build/Debug

Test Environment

How to set up a test environment for manual testing?
