How do you stop qmake from trying to strip all installed files? | MythTV | Dev
When adding some files to INSTALLS, they are stripped if they are excecutables.

To avoid using strip, you can update "QMAKE_STRIP" variable and force stripping executables one by one using ".extra":
```
target.extra = strip $${DESTDIR}/$(TARGET)
QMAKE_STRIP = echo # Avoid striping unwanted files (which will not work)
applibs.files = $${DESTDIR}/*.so*
applibs.path = $$EXPORT_LIBPATH
INSTALLS += applibs
```

GitHub - Fylhan/qompoter: Dependency manager for Qt / C++.

Hier, j'ai releasé la v0.2.6 de Qompoter, a C++/Qt dependency manager. Outre les améliorations apportées au truc (recherche récursive des paquets, numéros de versions flous du genre v1.*, recherche des paquets dans Inqlude), cela m'a aussi permis de découvrir les scripts d'auto-complémetion Bash ! Et je surkiffe taper qompoter tab tab et voir la liste des actions possibles apparaître "install export inqlude jsong". C'est beau Linux.

Qompoter a atteint un niveau de maturité suffisant pour les petits projets, alors n'hésitez pas ! Vos retours sont les bienvenues.
