I am new to JUCE and trying to use the CMake workflow. I copied the example GUI app from the repo, and can build it, but as soon as I try to use other classes and includes I get linker errors:
FAILED:

# Example GUI App CMakeLists.txt
# To get started on a new GUI app, copy this entire folder (containing this file and C++ sources) to
# a convenient location, and then start making modifications. For other examples of CMakeLists for
# GUI apps, check `extras/Projucer` and `examples/DemoRunner` in the JUCE repo.
# The first line of any CMake project should be a call to `cmake_minimum_required`, which checks
# that the installed CMake will be able to understand the following CMakeLists, and ensures that
# CMake's behaviour is compatible with the named version. This is a standard CMake command, so more
# information can be found in the CMake docs.

# If you've installed JUCE somehow (via a package manager, or directly using the CMake install
# target), you'll need to tell this project that it depends on the installed copy of JUCE. If you've

# include that subdirectory as part of the build.

# `juce_add_gui_app` adds an executable target with the name passed as the first argument
# (GuiAppExample here). This target is a normal CMake target, but has a lot of extra properties set
# up by default. This function accepts many optional arguments. Check the readme at
# `docs/CMake API.md` in the JUCE repo for the full list.

# `juce_generate_juce_header` will create a JuceHeader.h for a given target, which will be generated
# into your build tree. This should be included with `#include <JuceHeader.h>`. The include path for
# this header will be automatically added to the target. The main function of the JuceHeader is to
# include all your JUCE module headers; if you're happy to include module headers directly, you
# probably don't need to call this.

# `target_sources` adds source files to a target. We pass the target that needs the sources as the

# `target_compile_definitions` adds some preprocessor definitions to our target. In a Projucer

# need that's not on by default, check the module header for the correct flag to set here. These

# definitions, pick unique names that are unlikely to collide! This is a standard CMake command.

CLion itself recognizes any symbols like eg the audio format class just fine through an include. I don’t understand how this is all supposed to work. Do I still have to separately add modules in the Cmakelists file? How do I do this? I cannot find any information about it.
