c++ - 无法使用 fixup_bundle() 与 Qt 创建可移植包

Question

我已经在其他帖子上搜索过这个问题，但目前还没有。所以我来了。

我想创建一个可移植的包。便携，如“我可以在任何 OS X 机器上运行它，即使我需要的库 (Qt) 没有安装”。不幸的是，我不知道如何使用 fixup_bundle()(这似乎是正确的工具)来实现这个目标。

这是我最小的 CMake 生成的 C++ 项目:

主要.cpp

#include <QString>
#include <iostream>

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 bundle.cmake)

捆绑.cmake

INCLUDE(BundleUtilities)
fixup_bundle(test.app "" "")

这是生成的 test.app 结构

test.app
 - Contents
    - Info.plist
    - Frameworks
       - QtCore.framework
          - Versions
             - 4
                - QtCore
    - MacOS
       - test

所需的一切似乎都在包中。一切都顺利编译，运行良好，但是当我调用 fixup_bundle 时，这就是我得到的:

Install or copy the item into the bundle before calling fixup_bundle.
Or maybe there's a typo or incorrect path in one of the args to fixup_bundle?

有依赖路径(由 otool -L 给出):

显然，fixup_bundle 没有修复二进制文件的包，它们的 id 仍然设置为我机器的路径。

我在这个简单的例子中做错了什么？

Answer 1

我在 CMakeLists.txt 的顶部添加了这一行

set(CMAKE_INSTALL_PREFIX ${CMAKE_BINARY_DIR})

就是这样。

显然，默认情况下，CMAKE_INSTALL_PREFIX 在我的机器上设置为/usr/local。如果将其更改为我当前的工作目录解决了问题，则意味着 CMake 正在尝试对/usr/local 执行一些操作(这是不允许的)。那么为什么报错信息中没有提到这样的权限访问错误呢？

不知道是我看的文档不够多，还是文档需要一些精确...
