Add CMake project

[irov]

can I create a pull request and add to this project CMakeLists.txt?

Given that there are Premake-generated projects for each platform and architecture that is supported, we do not need Cmake. Some of the original reasoning is available in this blog post:

Adding Cmake in addition to Premake would increase the maintenance overhead and I already do not have a lot of free time. I am not likely at all to accept a Premake pull request as a result of all these reasons.

@irov I think a battle-tested CMakeLists.txt would be very much appreciated by the community even if not upstreamed into the main project :))

There is an unofficial cmake file in vcpkg you can work with. https://github.com/microsoft/vcpkg/tree/master/ports/nativefiledialog
