🚀 Cross-compile for Windows (mingw-w64)

[coalio]

Useful information

As of now, this utility can only be used in Linux due to the usage of functions that perform Linux system calls such as mkdir. The umask is also defined at the first line of the int main() function. [main.cpp:19]

I believe this utility would be useful for Windows developers that don't want to use WSL (or are running older Windows releases such as 7). The integration should not be complicated at all. However, some time must be spent in order to do this.

As a requirement, the CMake specification must also allow to cross-compile for Win32 from Linux using the mingw-w64 toolchain.

Since I wrote this issue, several enhancements were made to the source code and now we're not using either mkdir or umask at all.

However, adding a CMake target for cross-compiling is still a pending task. The issue name will be modified to reflect the actual issue now.
