[tde-devels] fatal error: ft2build.h: No such file or directory

Hello again! I downloaded the source of tqt3 to build it but the build cancelled with the following error: In file included from qximinputcontext.h:68, from qximinputcontext_x11.cpp:37: ../../../../include/private/qt_x11_p.h:154:14: fatal error: ft2build.h: No such file or directory 154 | # include <ft2build.h> | ^~~~~~~~~~~~ Do you know how to fix this? I installed the package libfreetype6-dev like some people suggested on the internet but that didn't help me so solve the problem. Kind regards, Christoph
