I don't need to.  The packages are already listed in INSTALL:

101:    libcrypto++-dev libssl-dev qml-module-qtpositioning qml-module-qtlocation
112:    libcrypto++-dev libssl-dev qml-module-qtpositioning qml-module-qtlocation

for both debian and ubuntu.  In my case (debian unstable) those 
packages were removed when I did a major qt5 upgrade.

In any case, the point I'm trying to make is subsurface should _not_ 
segfault because of that.  That case should be properly error handled, 
shouldn't it?

The two libraries:

/usr/lib/x86_64-linux-gnu/qt5/qml/QtLocation/libdeclarative_location.so
/usr/lib/x86_64-linux-gnu/qt5/qml/QtPositioning/libdeclarative_positioning.so

are probably loaded at runtime (maybe with dlopen?).  The code that 
does that appears not to do error handling.

It also appears the cmake rules don't check either.  Shouldn't they?
