Well, one could go ‘the hard way’. But that would require making the project subdirs based (or the like) and adding the open ssl locally to the project. Then you could install it to /usr/share/appname/lib … I only have one project like that (with a small c++ library) and that’s manageable. It’s doable, for sure. I just wouldn’t do it
Just to illustrate:
Excerpt top project:
SUBDIRS += \
libsynth \
simplesynth
Excerpt the lib pro file:
CONFIG += staticlib
target.path=/usr/share/harbour-simplesynth/lib
Excerpt the main app pro file:
LIBS += -L$$OUT_PWD/../libsynth/ -lsynthetizer
QMAKE_RPATHDIR += /usr/share/$${TARGET}/lib
SOURCES += src/harbour-simplesynth.cpp \
src/synthesizer.cpp
# Headers
HEADERS += ../libsynth/include/libsynth.hpp \
src/synthesizer.h
INCLUDEPATH += ../libsynth/ \
src/
But I’m really hoping the author of the package responds.
