How to correctly include C++ static library to iOS project

Question

I have a project which contains C++ static library (mylib.a), header for it (mylib.h) and objc class which use functions of this library (.h/.m). I'm trying to copy this files to another project but every time I'm getting linking error.

Undefined symbols for architecture armv7
_ClassNameFromLibrary
referenced from:
      -[LibraryUserClass init] in LibraryUserClass.o
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

This library works correctly in another project. I tried to copy all setting from working project and it doesn't help.

Try to add libxml2.dylib and libz.dylib In Link Binary With Libraries.

If that does not work, please refer this question answer: Undefined symbols for architecture armv7
