Cmake - proposal / WIP

[ahkok]

This is a shot across the bow to make this project easier to consume for everyone. With CMake, you can continue to use MSVC, build on Linux/Unix etc. And it will be much easier for consumers to actually use this software:

$ mkdir build
$ cd build
$ cmake ..
$ make
$ sudo make install

This makes packaging for all distributions trivial.

This is NOT finished. This is just an initial step showing how simple this can look if done right.

• Linux works. The other OSs I'll need to convert the specific compilation flags still (I can't test or use windows)
• daemon/client compile as well
• make install also works
• all the binaries compile/link OK
• added proper version numbering (1.0.0)
• create static internal library works

I've also reorganized the code to make sure there's no duplicate Cpp/H files around. Windows build may require a few more files to be moved to src and included in the build sequence, or otherwise fixed up.

There's a ton more here that can and needs to be done, but I'd like @opcm folks to sniff at this and get warmed up for doing this change, since it will make the project trivial to consume for all customers (not just clearlinux users).

Note: this was ~ 3 hours of work. Please don't let this go to waste.

This can drop ../ if the directory is already in the includes fro include_directories()

@ahkok this is great! Thank you for making this proposal. cmake will really pay off if we can join two current Makefile (Linux/*BSD/OSX) and MSVC project files processes. BTW you can check your PR builds on OSX here: https://travis-ci.org/opcm/pcm/pull_requests
I am not sure why github dropped travis from pcm CI checks (need to look into it)

I welcome changes in this direction, please continue with this, it is very much appreciated!

Next I'll need to work on MSVC/Windows builds and Mac/BSD - Windows will be a little bit more complex.

Not much progress today. Twiddled on MacOS builds yet but I think we may need to replace the xcodebuild section - I'm looking to see if there's examples where people have done similar things, but nothing came up yet.

FWIW I think this will take a few weeks at least to iron out for MacOS and Windows. Given that I'm a Linux dev only I'll need to find some cross platform folks that can help with this.

thanks. Now we have moved to cmake in the master branch.
