MinGW support

[ark0f]

Why POCO doesn't have MinGW support? I think it is not difficult. I can even add support personally.

[aleks-f]

if you want to own it, it's yours. send pulls with fixes and if they don't break other builds, they will be merged. see with @zosrothko if there is space in CI environment for it

[zosrothko]

On AppVeyor, there is space.. on VSTS, it remains 25GB but one should keep it for VS addition. Thus I would suggest to CI the MinGW on AppVeyor. @Good-Pudge Please ask for a account on Slack to easy the communication

[aleks-f]

yes, appveyor will be fine. @Good-Pudge I have sent you invite for slack

For the error in PocoMacros.cmake, these modified code chunks should work, at least with 1.9.0:

    # be set up anyway

    get_filename_component(kit_dir "[HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows Kits\\Installed Roots;KitsRoot]" REALPATH)
    get_filename_component(kit81_dir "[HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows Kits\\Installed Roots;KitsRoot81]" REALPATH)
    if (X64)

Hmm, it seems the issue has been fixed in develop for systems that have mc.exe, though this may be useful for anyone looking to cross-compile Windows binaries on Linux.

I'll leave this open for now if anyone care to carry the changes from develop over to devel (sorry that 2.0 did not happen, but we simply don't have resources to support two lines of development/support).
