No application installed for "shared library" files

[Geng.Y]

Hi, I just cloned from github a qt project and make it without any error, but when I try to run it, I got the error as follows.

I googled this problem and find the solution to add QMAKE_LFLAGS += -no-pie in .pro file. Then I tried again. It doesn't show the erorr again but also doesn't run. Can you help me figure out this problem? Bt the way, I didn't instal Qt Creator, is that necessary to install?
Thank you~

It happens on Ubuntu 18.04 LTS x64 ,Any project without QMAKE_LFLAGS += -no-pie in their .pro file
by the way dear @Geng-Y please remove build folder and try to build the project again the problem will go away.

For more information have a look at:

To see what PIE an no-pie is.
