CMake依赖于“所有”目标从自定义目标 [英] CMake depend on "all" target from custom target

问题描述

我正在制作一个需要以高级方式打包的图书馆，作为其中的一部分，我有一个包含这些行的脚本：

I'm making a library that needs to be packaged in a fancy way, and as part of that, I have a script that contains these lines:

#only install the lib component, nd put in the a special directory
ADD_CUSTOM_TARGET(o_destdir_install
  COMMAND DESTDIR=${CMAKE_BINARY_DIR}/o_package ${CMAKE_COMMAND} -DCOMPONENT=lib -P cmake_install.cmake
  DEPENDS ${CMAKE_BINARY_DIR}/cmake_install.cmake
  COMMENT "Building o_package directory with DESTDIR"
  )
ADD_DEPENDENCIES(o_destdir_install all preinstall)

我从旧的UseDebian.cmake dpkg生成器中找到了这个代码，但它不会生成所有和预安装，安装。使我的目标取决于一个非内置的目标似乎工作，但我不能依赖任何内置的目标，它似乎。我如何让这个工作？

I've found this code from the old UseDebian.cmake dpkg builder, however it does NOT build all and preinstall before it runs the install. Making my target depend on a non-built-in target seems to work, but I can't depend on any built-in targets it seems. How can I get this to work?

此外，如果我可以依赖单个组件安装，最好没有黑客调用cmake，但是我可以很好。

Also it would be nice if I could depend on a single component install preferably without the hacking calling of cmake, but I'm fine either way

推荐答案

代替合并自己的安装目标，你应该使用 install（CODE） 表单：

Instead of hacking together your own install target, you should just piggy-back on the existing one using the install(CODE) form:

install(CODE "execute_process(COMMAND DESTDIR=${CMAKE_BINARY_DIR}/o_package ${CMAKE_COMMAND} -DCOMPONENT=lib -P cmake_install.cmake")
