+ ${NDKROOT}/sources/cxx-stl/gnu-libstdc++/include
+ ${NDKROOT}/sources/cxx-stl/gnu-libstdc++/libs/armeabi-v7a/include
+ ${ProjDirPath}/../../sdk/native/jni/include
+
+ The last path should be changed to the correct absolute or relative path to OpenCV4Android SDK location.
+
+ This should eliminate those syntax errors marks in Eclipse C++ editor.
