Detailed steps on how to reproduce the bug

JUCE: 7.0.5 Tooling: CMake

Building a synth audio plugin with CMake generated NMake Makefile, VST3 support fails to compile resources:

[ 48%] Built target MySynth
[ 51%] Building RC object CMakeFiles/MySynth_Standalone.dir/MySynth_artefacts/JuceLibraryCode/resources.rc.res
'Synth\""' is not recognized as an internal or external command,
operable program or batch file.
NMAKE : fatal error U1077: 'C:\PROGRA~2\WI3CF2~1\10\bin\100190~1.0\x64\rc.exe' : return code '0xff'
Stop.
NMAKE : fatal error U1077: '"C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.30.30705\bin\HostX64\x64\nmake.exe"' : return code '0x2'
Stop.
NMAKE : fatal error U1077: '"C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.30.30705\bin\HostX64\x64\nmake.exe"' : return code '0x2'
Stop.

The problem is likely related to resource compilation which eventually invokes this line:

The problem is likely due to the | symbol in the VST3 audio category being interpreted as a pipe symbol.

Not enabling the VST3 plugin generation, or making the plugin an effect resolves the issue.

What is the expected behaviour?
