Plugin examples not compiling due to cmake prefix path not set in CMakeLists.txt

[siksal]

Environment

• OS Version: Ubuntu 24.04
• Source or binary build? Source (gz-plugin3) with this latest commit

Description

• Expected behavior: Compile the example plugin according to the README
• Actual behavior: Compilation error after running cmake ..

Steps to reproduce

1. Install gz-plugin3 from source according to this README
2. Go to the examples directory

mkdir build
cd build
cmake ..

Output

Additional Note

Cmake prefix path should be set in the CMakeLists.txt in the example directory to locate the necessary file for gz-plugin.

You'll need to install gz-plugin (sudo make install) so that it's available for the example. The example is designed to be a standalone project so that you can move it anywhere and customize it for your needs, but this requires the assumption that gz-plugin is either installed from binaries or if building from source, that you have compiled with -DCMAKE_INSTALL_PREFIX=/usr and ran sudo make install. There are other ways to accomplish this, but these are the easiest ones.

Thank you. It worked that way.
