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.
A recent commit added the file src/stc/PlatWXcocoa.mm needed for wxSTC
with the cocoa port. This commit modifies the build system files to
use this new file when it is needed.
The auto-generated header causes undefined members and identifiers in the
standard c++ headers when using clang on macOS or Windows.
Do not disable precompiled headers entirely but use the main Scintilla
header as prefix header so there is at least a small speedup.
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.
