Linking errors: building C++ Poco statically for MinGW on Windows with CMake

Question

I want to build newest Poco C++ Libraries Complete Edition on Windows statically (libraries only Poco::Foundation and Poco::Zip, without samples and tests) for MinGW (which is delivered by QT Creator).

So first I download and unpack the Windows-version library from home page https://pocoproject.org/download/index.html it is now version poco-1.7.8p3-all

Now I have to change MC settings for different configuration than VS, so I have to change file $(POCO_BASE)/cmake/PocoMacros.cmake and after IF

if ("${CMAKE_GENERATOR}" MATCHES "Visual Studio") ... endif ()

add lines:

 get_filename_component(sdk_dir "[HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Microsoft SDKs\\Windows;CurrentInstallFolder]" REALPATH)
 set(sdk_bindir "${sdk_dir}/bin")

I use CMake command:

cmake -G "MinGW Makefiles" -DENABLE_CRYPTO=OFF -DENABLE_NET=OFF -DENABLE_XML=OFF -DENABLE_DATA=OFF -DENABLE_MONGODB=OFF -DENABLE_PAGECOMPILER=OFF -DENABLE_PAGECOMPILER_FILE2PAGE=OFF -DENABLE_NETSSL=OFF -DPOCO_STATIC=ON -DCMAKE_INSTALL_PREFIX:PATH=C:\Users\user\Desktop\stackPocoStatic\built

Output:

then I run make:

PS C:\Users\user\Desktop\stackPocoStatic\poco-1.7.8p3-all> mingw32-make.exe
[ 43%] Built target Foundation
[ 60%] Built target XML
[ 63%] Built target JSON

...

and it looks OK, so then I want to compile and run code e.g.:

#include <iostream>
#include <fstream>
#include <Poco/Zip/Compress.h>

int main( int argc, char * argv[] )
{
    std::ofstream outputZipArchive("archive.zip", std::ios::binary);

    Poco::Zip::Compress compressor( outputZipArchive, true );
    for( unsigned i = 1; i < argc; ++i )
    {
        const char * fileToZip = argv[i];
        std::cout << i << ") Adding: " << fileToZip << std::endl;
        try
        {
            compressor.addFile( fileToZip, fileToZip );
        }
        catch(const Poco::FileNotFoundException & e)
        {
            std::cerr << "Can not add file " << fileToZip << ", because: " << e.what() << std::endl;
        }
    }

    compressor.close();
    outputZipArchive.close();
}

during compilation I see linking error:

collect2.exe: error: ld returned 1 exit status 

The interesting thing is when I run ./configure without option -DPOCO_STATIC=ON:

cmake -G "MinGW Makefiles" -DENABLE_CRYPTO=OFF -DENABLE_NET=OFF -DENABLE_XML=OFF -DENABLE_DATA=OFF -DENABLE_MONGODB=OFF -DENABLE_PAGECOMPILER=OFF -DENABLE_PAGECOMPILER_FILE2PAGE=OFF -DENABLE_NETSSL=OFF -DCMAKE_INSTALL_PREFIX:PATH=C:\Users\user\Desktop\stackPocoDynamic\built

then

mingw32-make.exe && mingw32-make.exe install

then compile:

PS C:\Users\user\Desktop> g++.exe z.cc -isystemC:\Users\user\Desktop\stackPocoDynamic\built\include -LC:\Users\user\Desk
top\stackPocoDynamic\built\lib\  -lPocoFoundation -lPocoZip

there are no linking errors. Of course this time I need .dlls (libPocoZip.dll and libPocoFoundation.dll) to run code:

 .\a.exe file.txt
 1) Adding: file.txt

Of course I've tried: Static and Dynamic/Shared Linking with MinGW -Wl,-Bstatic:

PS C:\Users\user\Desktop> g++.exe -Bstatic z.cc -isystemC:\Users\user\Desktop\stackPocoStatic\built\include -LC:\Users\user\Desktop\stackPocoStatic\built\lib\  -lPocoFoundation -lPocoZip  

I've also tried to add option -static: Statically linking libraries in MinGW

PS C:\Users\user\Desktop> g++.exe z.cc -static -isystemC:\Users\user\Desktop\stackPocoStatic\built\include -LC:\Users\us
er\Desktop\stackPocoStatic\built\lib\  -lPocoFoundation -lPocoZip

Unfortunately there are still linking errors.

I've noticed similar linking errors when compiling with MSYS on Windows:

./configure  --static --no-tests --no-sharedlibs --omit=XML,JSON,Util,NetSSL_OpenSSL,Data,Data/SQLite,Data/ODBC,Data/MySQL,MongoDB,PageCompiler,PageCompiler/File2Page,Crypto,PDF,CppParser --config=MinGW 

So My question is: Is it possible to compile POCO C++ libraries for MinGW statically on Windows?
