TheCharlatan 8dd2a20ff8 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.

# - Try to find readline include dirs and libraries
#
# Usage of this module as follows:
#
# find_package(Readline)
#
# Variables used by this module, they can change the default behaviour and need
# to be set before calling find_package:
#
# Readline_ROOT_DIR Set this variable to the root installation of
# readline if the module has problems finding the
# proper installation path.
#
# Variables defined by this module:
#
# READLINE_FOUND System has readline, include and lib dirs found
# GNU_READLINE_FOUND Version of readline found is GNU readline, not libedit!
# LIBEDIT_FOUND Version of readline found is libedit, not GNU readline!
# Readline_INCLUDE_DIR The readline include directories.
# Readline_LIBRARY The readline library.
# GNU_READLINE_LIBRARY The GNU readline library or empty string.
# LIBEDIT_LIBRARY The libedit library or empty string.
