Can't use fixup_bundle() to create a portable bundle with Qt

Question

I already searched this issue on other posts, but nothing so far. So here I am. I'd like to create a bundle that is portable. Portable as in "I can run it on any OS X machine, even if my required libs (Qt) are not installed". Unfortunately, I can't figure out how to use fixup_bundle() (which seems the right tool for it) to achieve this goal. Here is my minimal CMake generated C++ project : main.cpp ``` #include #include int main() { QString s("Hello, world!"); std::cout << s.toStdString() << std::endl; return 0; } ``` CMakeLists.txt ``` cmake_minimum_required(VERSION 2.8.11) project(test) # That part because I use a custom build of Qt. That's not the # relevant part (I guess?) FILE(GLOB QTROOTS path_to_qt/Qt-4.8.1/osx/bin/qmake) find_program(QT_QMAKE_EXECUTABLE NAMES qmake PATHS ${QTROOTS}) find_package(Qt4 COMPONENTS QtCore REQUIRED) include(${QT_USE_FILE}) add_executable(test MACOSX_BUNDLE main.cpp) target_link_libraries(test ${QT_LIBRARIES}) install(SCRIPT bund…

Accepted Answer

I added this line at the top of my CMakeLists.txt

```
set(CMAKE_INSTALL_PREFIX ${CMAKE_BINARY_DIR})
```

And that was it.

By default, apparently, CMAKE_INSTALL_PREFIX is set to /usr/local on my machine. If changing it to my current working directory solved the issue, that means CMake was trying to perform some operations on /usr/local (which it is not allowed to do). So why the error message does not mention such a right access error?

I don't know if I haven't read enough documentation, or if the documentation needs some precisions...
