linux - CPack 构建输出位置错误的外部 autogen 项目

Question

我正在尝试在基于 autogen 的项目上使用 CMake ExternalProject_Add 构建 debian。该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。我已经尝试执行额外的 CMake install() 命令，它确实有效，但我仍然在前缀目录位置获得目标输出的额外副本。

这是完整的 CMakeLists.txt

set(CPACK_PACKAGE_FILE_NAME ${CPACK_DEBIAN_PACKAGE_NAME}_${CPACK_DEBIAN_PACKAGE_VERSION}_${CPACK_DEBIAN_PACKAGE_ARCHITECTURE})

include(CPack)

如果我添加一个 install(DIRECTORY ${SPHINXBASE_INSTALL_DIR} DESTINATION ${CMAKE_PREFIX_PATH}) 我最终得到了正确的安装，但仍然有额外的副本尝试安装在 ${ SPHINXBASE_INSTALLDIR}。如果我在 ExternalProject_Add 中以没有 PREFIX 的方式运行构建，它工作正常，但我不希望构建以 sudo 运行。

有什么方法可以强制 CPack 使用 ${SPHINXBASE_INSTALL_DIR} 并将其安装到 ${CMAKE_PREFIX_PATH}？

Answer 1

我今天遇到了同样的问题。实际上，如果您运行 make package，cmake 将运行，包括您不想要的 make install 部分。尝试仅将“cpack”用作命令行。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，它会执行 make install。cpack 首先将安装前缀设置为一个临时目录，然后运行 ​​make install。
