CMake-CPack包安装路径噩梦 [英] CMake-CPack Package Installation Path Nightmare

问题描述

CMake-CPack 让我沮丧了将近一周.

I've been frustrated by the the CMake-CPack for almost one week.

不好的是 CMake-CPack 在线文档没有很好地记录这部分.

The bad thing is the CMake-CPack online documentation does not document this part well.

谷歌搜索后，我发现要使用这个变量:

After googling, I found this variables to use:

CPACK_PACKAGING_PREFIX          # NOT documented
CMAKE_INSTALL_PREFIX            # Documented, but the behavior seems weird
CPACK_INSTALL_PREFIX            # NOT documented
CPACK_PACKAGE_INSTALL_DIRECTORY # Documented, but this variable does NOT work as the online document described
CPACK_PACKAGING_INSTALL_PREFIX  # NOT documented

我要做的是:使用 fakeroot make package 打包一个 Debian 包，当该包由 sudo dpkg -i MyProgramPackageName 安装时，将其安装到 /usr/local，带有一个子目录 MyProgramPackageName.也就是说，所有文件都应该安装在/usr/local/MyProgramPackageName-V.1.2.3下.

What I am trying to do is: package a Debian package using fakeroot make package, when the package is installed by sudo dpkg -i MyProgramPackageName, install it to /usr/local, with a subdirectory MyProgramPackageName. That is, all files should be installed under /usr/local/MyProgramPackageName-V.1.2.3.

我一直在尝试(CMake 2.8.3 和 CMake 2.8.5)调整这些变量.我尝试了很多组合，但都失败了.

I've been trying (CMake 2.8.3 and CMake 2.8.5) to tune these variables. I tried so many combinations, but failed.

成功的唯一方法是:

Set(CPACK_PACKAGING_INSTALL_PREFIX /usr/local/MyProgramPackageName-V.1.2.3)

但是这个变量甚至没有记录，并且无法保证行为.如果您对我的问题感到困惑，请告诉我何时使用 CPACK_PACKAGE_INSTALL_DIRECTORY?因为关于这个变量的文档描述非常吸引人，这确实是我想要的，但我就是无法让它工作.

But this variable is NOT even documented, and the behavior cannot be guaranteed. If you are confused with my question, please advise me when to use CPACK_PACKAGE_INSTALL_DIRECTORY? because the documentation description about this variable is really attractive, and it is really what I want, but I just could not make it working.

请给我建议.

彼得

推荐答案

我没有找到任何支持这一点的文档，但我确实找到了一些错误报告和电子邮件存档，似乎表明以下是你应该做的正在做:

I didn't find any documentation to support this, but I did find some bug reports and email archives that seem to suggest that the following is what you should be doing:

set(CPACK_SET_DESTDIR true)
set(CPACK_INSTALL_PREFIX /opt/MySuperAwesomePrefix-v.1.2.3)

如果未设置 CPACK_INSTALL_PREFIX，则默认为 CMAKE_INSTALL_PREFIX.现在 install(... DESTINATION dest) 的相对路径将在您的包文件中以 CPACK_INSTALL_PREFIX/dest 结束.这在我尝试生成 deb 文件时有效.

If CPACK_INSTALL_PREFIX is not set, it will default to CMAKE_INSTALL_PREFIX. Now relative paths from install(... DESTINATION dest) will end up as CPACK_INSTALL_PREFIX/dest inside your package file. This worked when I tried to generate a deb file.
