+No additional plugins are needed, the only thing you need to do is to set the CMake options correctly. When you open your mod's directory in CLion for the first time, you'll be met with an Open Project Wizard:

+Here you need to make sure that:
+
+1. Build type is set to Release or RelWithDebInfo, it **cannot** be Debug
+2. Toolchain is set to *Visual Studio*
+3. Generator is set to *Visual Studio 17 2022* or newer
+4. Build directory is set to *build*
+5. CMake options contains `-A win32`

+In the created configuration, click the *Target* dropdown and choose *All Targets*. You can also change the name to \
+something else than "Unnamed".

+reload CMake now, this run should end successfully with a message saying `[Finished]` at the end:
