Reproduction steps

1. If I run mkdir build && cd build && cmake .., the terminal returns :

CMake Error at CMakeLists.txt:14 (target_include_directories):
  Error evaluating generator expression:

    $<TARGET_PROPERTY:wasmedgePlugin,INCLUDE_DIRECTORIES>

  Target "wasmedgePlugin" not found.

2. If I run wat2wasm test.wat -o test.wasm && wasmedge test.wasm, the error message is :

Could you please check this? Should we use the wasi-logging as the example instead of this one?

[hydai]

The build command should be:

cd WasmEdge
cmake -Bbuild -DWASMEDGE_BUILD_EXAMPLE=ON .
cmake --build build

And we will encounter another error due to the plugin API changes:

/Users/hydai/workspace/WasmEdge/examples/plugin/get-string/getstring.cpp:97:9: error: no type named 'PluginRegister' in namespace 'WasmEdge::Plugin'
Plugin::PluginRegister Register(&Descriptor);
