я про второй ответ в теме, который

LIBS += -L/path/to -lpsapi

$ORIGIN and rpath

ld.so understands the string $ORIGIN (or equivalently ${ORIGIN}) in an rpath specification (DT_RPATH or DT_RUNPATH) to mean the directory containing the application executable. Thus, an application located in somedir/app could be compiled with gcc -Wl,-rpath,'$ORIGIN/../lib' so that it finds an associated shared library in somedir/lib no matter where somedir is located in the directory hierarchy. This facilitates the creation of «turn-key» applications that do not need to be installed into special directories, but can instead be unpacked into any directory and still find their own shared libraries.

немного описания

опечатался, кстати, $ORIGIN

Собери либу статикой, пейсатель ;)
