+StgSharp.Native layout

+Conventions:
+- src/        : project C sources and CMakeLists.txt calling add_library/add_executable
+- include/    : public headers (if used)
+- external/   : third-party libraries, each library lives in its own folder
+    - <libname>/
+        - head/   : header files for the library
+        - lib/    : static or shared lib files (or CMake build for that lib)
+
+The root `CMakeLists.txt` in this folder includes `ExternalLibs.cmake` if present.
