nvm i found solution on my own:
changed in CMakeLists.txt cpp standard:
from:

set_target_properties(tfs PROPERTIES CXX_STANDARD 20)
set_target_properties(tfs PROPERTIES CXX_STANDARD_REQUIRED ON)

to:

set_target_properties(tfs PROPERTIES CXX_STANDARD 17)
set_target_properties(tfs PROPERTIES CXX_STANDARD_REQUIRED ON)
