CMake-CPack软件包安装路径的噩梦 [英] CMake-CPack Package Installation Path Nightmare

问题描述

我已经对CMake-CPack感到沮丧了将近一个星期.

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内容.

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

谷歌搜索后，我发现该变量可以使用:

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

我想做的是:使用fakeroot make package打包Debian软件包，当sudo dpkg -i MyProgramPackageName安装软件包时，将其安装到/usr/local中，并带有子目录MyProgramPackageName.也就是说，所有文件都应安装在/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.

唯一成功的方法是:

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

但是此变量甚至都没有记录，因此无法保证其行为.如果您对我的问题感到困惑，请告诉我何时使用CPACK_PACKAGE_INSTALL_DIRECTORY?因为有关此变量的文档描述确实很吸引人，而且确实是我想要的，但我无法使其正常工作.

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.

请告诉我.

彼得

推荐答案

我没有找到任何文档来支持此操作，但是我确实找到了一些错误报告和电子邮件归档，这些文件似乎暗示着以下内容应该是您应该做的.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，它将默认为CMAKE_INSTALL_PREFIX.现在，来自install(... DESTINATION dest)的相对路径将最终以CPACK_INSTALL_PREFIX/dest形式出现在您的包文件中.当我尝试生成deb文件时，此方法有效.

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.
