Bug #3982
Updated by Alex Afanasyev about 5 years ago
Snippet to reproduce:
```
#include <ndn-cxx/util/logger.hpp>
NDN_LOG_INIT(MyLogModule);
int
main()
{
NDN_LOG_FATAL("my-fatal");
}
```
Expected: code compiles with `g++ -o x -std=c++14 -std=c++11 x.cpp $(pkg-config --cflags --libs libndn-cxx)`
Actual:
```

`g++ -o x -std=c++11 x.cpp $(pkg-config --cflags --libs libndn-cxx) -DBOOST_LOG_DYN_LINK` works fine.
`-DBOOST_LOG_DYN_LINK` argument should be added into pkg-config output.
