Cutter plugin: LLVM ERROR: inconsistency in registered CommandLine options

[re-fox]

After building the Cutter plugin for retdec-r2plugin, Cutter will no longer start and throw the following error:

Setting PYTHONHOME = "/tmp/.mount_CutterWmruTW/usr"  for AppImage.
PYTHONHOME = "/tmp/.mount_CutterWmruTW/usr"
Setting r2 prefix = "/tmp/.mount_CutterWmruTW/usr"  for AppImage.
Setting r2 plugins dir = "/tmp/.mount_CutterWmruTW/usr/share/radare2/plugins"
: for the -W option: cl::alias must have argument name specified!
: CommandLine Error: Option 'bitcode-mdindex-threshold' registered more than once!
LLVM ERROR: inconsistency in registered CommandLine options
QMutex: destroying locked mutex

I used the following build instructions:

git clone https://github.com/avast/retdec-r2plugin
cd retdec-r2plugin
mkdir build && cd build
cmake .. -DBUILD_CUTTER_PLUGIN=ON -DCMAKE_INSTALL_PREFIX=~/.local/ -DCMAKE_LIBRARY_PATH=/usr/lib/gcc/x86_64-redhat-linux/10/
make -j4
make install

After building the plugin I can confirm it is working from the R2 CLI

$ r2 -A /bin/ls

Usage: pdz   # Native RetDec decompiler plugin.

I am using the latest Cutter AppImage and can confirm when launching Cutter with the --no-plugins options, it will run.
