Question

我正在尝试使用CMake ExternalProject_Add在基于autogen的项目上构建debian。项目安装到我设置的任何前缀目录（默认为/usr/local）。问题是，当我在项目上运行make package时，生成的debian使用该前缀目录而不是/usr/local。我已经尝试了一个额外的CMake install()命令，它可以正常工作，但我仍然可以在前缀目录位置获得额外的目标输出副本。

这是完整的CMakeLists.txt

include(CPack)

如果我添加install(DIRECTORY ${SPHINXBASE_INSTALL_DIR} DESTINATION ${CMAKE_PREFIX_PATH})，我最终会得到正确的安装，但仍有额外的副本试图在${SPHINXBASE_INSTALLDIR}安装。如果我在PREFIX中运行构建为没有ExternalProject_Add的sudo，它可以正常工作，但我不希望构建以sudo身份运行。

我是否可以通过某种方式强制CPack获取${SPHINXBASE_INSTALL_DIR}并仅将其安装到${CMAKE_PREFIX_PATH}？

Answer 1

我今天遇到了同样的问题。实际上，如果你运行make package，cmake将会运行，包括你不想要的make install部分。仅使用“cpack”作为命令行。它将直接构建一个包。

你也可以这样做：DESTDIR = / tmp / truc make package

make package首先运行cmake，它执行make install。 cpack首先将安装前缀设置为临时目录，然后运行make install。

CPack构建外部自动项目，输出位置不良
