Some analysis:

FT_Property_Set is declared in ftmodapi.h (https://github.com/openjdk/jdk/blob/4b463ee70eceb94fdfbffa5c49dd58dcc6a6c890/src/java.desktop/share/native/libfreetype/include/freetype/ftmodapi.h#L413). The header file is properly included by freetypeScaler.c:

https://github.com/openjdk/jdk/blob/4b463ee70eceb94fdfbffa5c49dd58dcc6a6c890/src/java.desktop/share/native/libfontmanager/freetypeScaler.c#L46

#include FT_MODULE_H


I'm puzzled why it cannot find `FT_Property_Set`. @vnkozlov Can you please provide more info about the build platform? Thanks
