Remove unused CMake code to get number of mono source files.
wxUSE_BASE=1 is also defined in wx_set_target_properties.
There seems no reason to define _LIB and DLL_EXPORTS, wx does not use it. They
were probably added because the vcxproj files have them.
Rename all library targets to start with wx. This way it does not use generic
names like base or core that could interfere with other libraries that add
include the wxWidgets project.
lzma.h could not be found when building with wxUSE_LIBLZMA on macOS. Add
the found include directories and libraries from find_package(LibLZMA)
to the base library.
For consistency, add the include directories and libraries of all
find_package usage.

uuid should be linked before oleacc, otherwise it causes multiple definition of `IID_IAccessible' (with MinGW64 gcc).
To simplify even more, specify all required libraries in wxTOOLKIT_LIBRARIES, in the same order as in the makefiles.
Add uxtheme library, it is required since wxUxThemeEngine wrapper has been removed.
Add CMake build system for libraries, tests and samples
update_files.py converts build/files into CMake format.
build/update-setup-h has been modified to update build/cmake/setup.h.in.
