Qt Creator failed on running program when linking /usr/local/lib

问题

Given the following simple project:

QT += core
QT -= gui

TARGET = ConsoleTest08
CONFIG += console
CONFIG -= app_bundle

TEMPLATE = app

SOURCES += main.cpp

LIBS += -L/usr/local/lib

With this simple main.cpp file:

int main(int argc, char *argv[])
{
    return 0;
}

When running from Qt Creator, I have the following error:

dyld: Symbol not found: __cg_png_create_info_struct
  Referenced from: /System/Library/Frameworks/ImageIO.framework/Versions/A/ImageIO
  Expected in: /usr/local/lib/libPng.dylib
 in /System/Library/Frameworks/ImageIO.framework/Versions/A/ImageIO
The program has unexpectedly finished.

It runs fine from the terminal.

Here is my config:

• OSX 10.9
• Qt 5.5.1 clang 64 biy
• Qt Creator 3.6.0

I lastely update to Qt Creator 3.6.0 so I suspect a bug.

I have libpng 1.6.21 installed via brew which seams to conflict with the ImageIO framework but I don't link explicitely none of them.

Any idea about what happened?

I solved my problem by unchecking this new Add build library search path to DYLD_LIBRARY_PATH and DYLD_FRAMEWORK_PATH checkbox in my project Run section:
