Bug Report: Compilation of es module

[ropinho]

When compiling es target on eo module, std::string is not recognized as a type.

On eoFunctor.h file, std::string is referenced but not is included.

The error log on cmake -DCMAKE_BUILD_TYPE=Release -DEO_ONLY=ON:

Solution: Add #include <string> on eoFunctor.h file
