Hello everyone,
I try to build a small Qt application (helloGUI) with a shared library (hello).
Here is my application and library tree:
├── CMakeLists.txt
├── gui
│ ├── CMakeLists.txt
│ ├── bundle.cmake
│ ├── include
│ │ └── MainWindow.hpp
│ ├── src
│ │ ├── MainWindow.cpp
│ │ └── main.cpp
│ └── ui
│ └── mainwindow.ui
└── lib
├── CMakeLists.txt
├── Hello.cpp
└── Hello.h
My root CMakeLists.txt add the two sub directory: lib then gui.
The lib CMakeLists.txt build a shared library (.dylib) and installed it inside
${CMAKE_INSTALL_PREFIX}/helloGUI.app/Contents/Libraries.
The gui CMakeLists.txt build my Qt bundle (helloGUI.app) and installed it
inside ${CMAKE_INSTALL_PREFIX} then launch the script bundle.cmake.
bundle.cmake contains:
include(BundleUtilities)
fixup_bundle("${CMAKE_INSTALL_PREFIX}/helloGUI.app"
"${CMAKE_INSTALL_PREFIX}/helloGUI.app/Contents/Libraries/libHello.dylib" "lib")
If I don’t install it, my application works just fine. But after installation,
I have some errors:

possible problems:
need more directories?
need to use InstallRequiredSystemLibraries?
run in install tree instead of build tree?

I see that the script search libHello.dylib inside Contents/MacOS but I don’t
understand why.
Can we set this path please?
Thank you.
