That's "normal" - I.e., things are the way Qt developers set them. They provide Qt5 CMake package config files, containing a lot of hardcoded relative paths there. So it's not easy to move .cmake files under some common prefix, outside of /usr/local/lib/qt5. N.B.: If you'd use x11/qt5 module, you'll get all the CMake setup for free, see /usr/ports/x11/qt5/qt5.port.mk (documentation is on the way). > 1.

Yes, known problem. CMake config file for Qt5Sql talks about all backends always. To be redone after fixing other urgent stuff. BTW, can't the Otter use the SQLite3 backend instead of SQLite2? The former is bundled with Qt5 itself because SQLite3 is part of base system nowadays. > 2. gcc warnings after compilation > Linking CXX executable otter-browser > /usr/local/lib/qt5/libQt5Script.so.0.0: warning: random() may return > deterministic values, is that what you want? > /usr/local/lib/qt5/libQt5WebKit.so.0.0: warning: strcpy() is almost > always misused, please use strlcpy() > /usr/local/lib/qt5/libQt5Core.so.0.0: warning: rand() may return > deterministic values, is that what you want? > /usr/local/lib/qt5/libQt5Script.so.0.0: warning: sprintf() is often > misused, please use snprintf() > /usr/X11R6/lib/libX11.so.16.0: warning: strcat() is almost always > misused, please use strlcat() > /usr/local/lib/libglib-2.0.so.4200.0: warning: stpcpy() is dangerous; do > not use it > /usr/local/lib/libglib-2.0.so.4200.0: warning: vsprintf() is often > misused, please use vsnprintf() That's "normal"... Well, except strcpy() in Qt5WebKit - strange, I thought I removed them all. I'll check again, thanks for reporting. The sprintf() worths looking into as well.
