Qmake: specify library search order - version conflicts?

Question

linux

Hello.
We use C++, Qmake on Linux. There was a problem of library versions conflict during assembly: if a library of one version is present in the system, it is it that is connected, despite the fact that another directory is specified in LIBS from the assembly tree.
Qmake automatically substitutes -L/usr/lib or -L/usr/lib/x86_64-linux-gnu for g++ arguments, and the rest of the flags follow.
Thus, if, for example, an older version of a library is installed on the system, it will be used during compilation, and this may cause build errors or other problems.
Please advise any way to solve this problem (except for removing the conflicting library from the system).

Answer 1

And you are in a PRO file when you write
LIBS += path_to_library
It turns out that you add to the end.
You can try to write not LIBS += but LIBS =, and list in the desired order
