poco/Data/include/Poco/Data/AbstractBinder.h
Miko 041e7feeb7 Add support for modules (#4999) 
* Add support for modules

* Use "" for inclusion

* Fix missing includes on Poco.Data module

* Add PDF and SevenZip modules, and match modules to build macros

* Add CI test

* Add missing link libraries in CMake

* Add remaining libraries DNSSD, CppParser and CppUnit. Changed some static declarations to inline to export

* We also need to forward the ENABLE_NETSSL_* macros

* Update CMakeLists files

* Add samples as requested, with DateTime and URI test for example

* Fix POCO_MODULES_INSTALL macro

* chore(CMake): Combine install macro for libraries and C++ modules into one macro.

* Apply testsuite changes and address include directories concerns

* Restore accidentally deleted build files

* Mistakenly added a file generated by CMake, removed.
