sorry to bother you, I'm trying to test the QtCaptureTest on Mac, when i run the command in QtCaptureTest directory > DYLD_LIBRARY_PATH=../build ./QtCaptureTest
, it came error,
x@x-Pro QtCaptureTest % DYLD_LIBRARY_PATH=../build ./QtCaptureTest zsh: no such file or directory: ./QtCaptureTest

when i tried to run this command at master directory openpnp-capture-master, x@x-Pro openpnp-capture-master % > DYLD_LIBRARY_PATH=../build ./QtCaptureTest zsh: no such file or directory: DYLD_LIBRARY_PATH=../build.

I'm new to code, and I will appreciate for u help .
