segfault in lv2_file_generator

1. Please provide an explicit title to the issue.
   compiled camomille according instructions - everything went well without errors/warnings.
   but when trying eg.: ./camomile -f ./Examples/Bulgroz

i got segfault:
Camomile - Plugin Generator
./builds/Bulgroz.vst3
generating ttl Bulgroz in ./builds/Bulgroz.lv2/Bulgroz.so
./camomile: line 243: 13046 Segmentation fault LD_LIBRARY_PATH=$PWD "$ThisPath/lv2_file_generator" "$plugin_output_dir/$plugin_name.lv2/$plugin_name.$LinuxLV2Extension" $plugin_name
mv: cannot stat '/home/tao/source/Camomile/Plugins/manifest.ttl': No such file or directory
mv: cannot stat '/home/tao/source/Camomile/Plugins/Bulgroz.ttl': No such file or directory

in builds dir i see created dirs bulgros.lv2 and bulgros.vst3 dirs with files:
-rw-r--r-- 1 tao tao 1609 Nov 9 15:12 Bulgroz.pd

-rw-r--r-- 1 tao tao 397 Nov 9 15:12 program.get.pd

but no manifest.ttl or Bulgroz.ttl

also if i do:
./lv2_file_generator ./builds/Bulgroz.lv2/Bulgroz.so Bulgroz

i got:
generating ttl Bulgroz in ./builds/Bulgroz.lv2/Bulgroz.so
Segmentation fault

2. Describe your environment

no idea what i am missing/doing wrong. ev. thnx for help - i would be very happy to use my pd patches as lv2 plugins with gui :)

This seems related to this #208. Can you confirm?

yes / sorry did not notice that #208 is about the same problem. so problem exists also under debian 10 64bit arch and is solved with: make CONFIG=Release

maybe to mention this in readme would be useful.
thnx for great wrapper! tested it with ardour, loaded more instances of the same plugin with different presets and it just works! 👍

Hello there . Thanks for this awesome project first of all .
This issue is still present when building according to instructions in README and docs .
At last on arm64 , if make is used without CONFIG Release after the build one gets segmentation faults in lv2_file_generator
