Migrate build system to cmake The content in this commit is not split in order to preserve working compilation. Once this is added to master, the old build script will no longer work and all existing build toolings will require changes. Monero's cmake directory's files need to be copied to this project's cmake directory in order for the linking and function definitions to work correctly. Monero-gui has its own version check and generate file in order to not conflict with monero's destination version files. Most of the source files that are currently in monero-gui's root directory are now moved to subdirectories. This is done to preserve compilation order properly and to give some content structure. The original CMakeList file included all headers it found in subdirectories. Make sure that they are set manually to evade linking errors. The current build script always checks out latest master of the monero submodule. The submodule rules in the current CMakeLists.txt file do not enforce. An override to compile master nevertheless can still be given with `-D DEV_MODE`. To enable the linux X11 xcb linking the libraries had to be hardcoded. There does not seem to be good support for this in pkgconfig, or in existing cmake checks. 2018-05-09 00:01:27 +00:00			`#ifdef __CLASSIC_C__`
