(CMake) Add a new CMake option to enable the new Unit Tests 8 years ago			`add_executable(unit_tests mainTestRunner.cpp`
Provide a gtestWrapper header to skip useless warnings 8 years ago			`gtestwrapper.h`
Export all symbols when running unit tests. Add dummy test for private code. I tried to use directly the private OBJECT library (exiv2lib_int) in the unit_tests targets, but the private objects have dependencies on the public symbols (circular dependency) and therefore it is impossible to test the private code with that approach with the current design of the library. Starting from CMake 3.3 we can use the variable CMAKE_WINDOWS_EXPORT_ALL_SYMBOLS to export all the symbols of a shared library: https://blog.kitware.com/create-dlls-on-windows-without-declspec-using-new-cmake-export-all-feature/ Even having the opportunity to use this variable (that will be only used when EXIV2_BUILD_UNIT_TESTS is enabled) the previous commits are still valid. It is interesting to clearly differentiate between the public and private code of the library. Enforcing this, make us think twice before putting code in the public part of the library. 8 years ago			`test_types.cpp`
