SUMMARY When I've try to install a single sub project, kdevelop runs install from root and try to compile all the project. This is working fine in kdevelp4. STEPS TO REPRODUCE 1. create a project A and two sub projects B & C like this. Both with INSTALL directive inside it. A ----- B | --- C B & C are shared libraries in my case and are independent. 2. clean all build secuence. 3. build B from from the project windows (right click on the project -> build) 4. install B from the project window (right click on the project -> install) OBSERVED RESULT The kdevelop try to compile A,B and C. What I could observe is that KDEVELOPS runs install from the root. EXPECTED RESULT The exepcted result is kdevelop runs install only on B project. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Debian 8 Kdevelop Image: KDevelop-5.5.0-x86_64.AppImage ADDITIONAL INFORMATION Something similar happends with build if you press on the folder instead of the target.
