CMake / CPack可以为一个项目生成多个NSIS安装程序吗？ [英] Can CMake/CPack generate multiple NSIS installers for a single project?

问题描述

我有一个项目（包含子项目），我想为其生成多个NSIS安装程序可执行文件，而不是在单个NSIS安装程序中列出多个组件。这可能吗？还是我需要将代码组织到单独的项目中？

I have a single project (with sub-projects) for which I would like to generate multiple NSIS installer executables, instead of having multiple components listed in a single NSIS installer. Is this possible? Or do I need to organize my code into separate projects?

推荐答案

一个可以提供CMake属性，例如 COMPONENT 可以设置为一组预定义的程序包名称中的值，例如：COMPONENT_1 | COMPONENT_2 | ... COMPONENT_X

One could provide a CMake attribute e.g. COMPONENT which can be set to a value from a predefined set of package names like: COMPONENT_1|COMPONENT_2|...COMPONENT_X

包名称甚至可以是与单个组件名称不对应的名称，而应与CPACK_COMPONENTS_ALL中添加的一组组件对应。如果COMPONENT等于ALL_COMPONENTS，则CPACK_COMPONENTS_ALL的值将包含所有可能的分量。

The package name could even be a name that does not correspond to a single component name but a set of components that would be added in the CPACK_COMPONENTS_ALL. If the COMPONENT is equal to ALL_COMPONENTS then the value of CPACK_COMPONENTS_ALL would contain all possible components.

cmake包装：

if (WIN32)
  set (CPACK_COMPONENTS_ALL ${COMPONENT})
  set (CPACK_PACKAGE_NAME ${COMPONENT})
  set (CPACK_COMPONENT_${COMPONENT}_DISPLAY_NAME "${COMPONENT}")
  set (CPACK_COMPONENT_${COMPONENT}_DESCRIPTION "${COMPONENT}")  
  set (CPACK_NSIS_DISPLAY_NAME "${COMPONENT}")
  set (CPACK_NSIS_PACKAGE_NAME "${COMPONENT}")
  set (CPACK_NSIS_INSTALL_ROOT "C:")
  set (CPACK_GENERATOR NSIS)
else()
  ...
endif()

要为每个组件创建一个安装程序，例如：

To create an installer for each COMPONENT you would run for example:

cmake -COMPONENT=COMPONENT_1 ../
nmake package
cmake -COMPONENT=COMPONENT_2 ../
nmake package
...
cmake -COMPONENT=COMPONENT_X ../
nmake package

请记住，由于二进制文件是基于 nmake程序包，随后对 cma的调用ke 和 nmake软件包将仅重新配置软件包，并且仅构建请求的COMPONENT（aka COMPONENT）

Bear in mind that since the binaries are build on the first execution of nmake package, the subsequent calls to cmake and nmake package will only re-configure the packaging and only build the requested COMPONENT(aka COMPONENT)
