Windows build fails a test

[oranja]

Hi,
Until now I was using Zipper on GNU/Linux and it worked well, but now I tried to build Zipper on a Windows 10 machine for the first time, and it seems to work, except for this one failing test:

C:\Projects\lib\zipper\build>libZipper-test.exe

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
libZipper-test.exe is a Catch v1.5.6 host application.
Run with -? for options

-------------------------------------------------------------------------------
Scenario: zipfile feed with different inputs
     Given: A Zip outputed to a file
      When: a file containing 'test file compression' is added and named
            'test1'
      Then: the zip file has one entry named 'test1.txt'
       And: extracting the test1.txt entry creates a file named 'test1.txt'
            with the text 'test file compression'
  And when: another file containing 'other data to compression test' and named
            'test2.dat' is added inside a folder 'TestFolder'
       And: the zip file has two entrys named 'test1.txt' and 'TestFolder/test2
            .dat'
       And: extracting the test2.dat entry creates a folder 'TestFolder' with a
            file named 'test2.dat' with the text 'other data to compression
            test'
  And when: adding a folder to the zip, creates one entry for each file inside
            the folder with the name in zip as 'Folder/...'
-------------------------------------------------------------------------------
C:\Projects\lib\zipper\test\file_zip_test.cpp(15)
...............................................................................

C:\Projects\lib\zipper\test\file_zip_test.cpp(105): FAILED:
  {Unknown expression after the reported line}
due to unexpected exception with message:
  invalid string position

===============================================================================
test cases:  2 |  1 passed | 1 failed
assertions: 50 | 49 passed | 1 failed

With a little help from debug prints, I can say that the exception is thrown from this call:
test/file_zip_test.cpp : 124 : zipper.add("TestFiles");

* To clarify, this is from master, without any of my changes from #16.
* Everything (Zipper, zlib 1.2.11) was compiled for x64, with MSVC 19 (VS 14.0 / 2015).

Here is the CMake summary:

My pull request (#18) should fix that.

This should be fixed as per @filonik PR (already merged). Thanks!
