Research direction

Start by reading the CMakeLists.txt in the issue and checking how yaml-cpp is found and linked against the application. Reproduce the undefined references with the shown linker output, then verify that the application links the matching yaml-cpp library; done when the build completes without those unresolved symbols.

Description

I am building an application that uses yaml-cpp but I get these errors:

/usr/bin/ld: CMakeFiles/transcribe.dir/transcribe.cpp.o: in function `returnVocabulary(std::string const&)':
transcribe.cpp:(.text+0x55786): undefined reference to `YAML::LoadFile(std::string const&)'

My CMakeLists.txt is as follows:
