build - Cmake 不尊重 CMAKE_INSTALL_PREFIX 的值

Question

我正在尝试从源代码安装很棒的 wm。所以我创建了一个构建目录并执行了以下命令:

cmake .. -DCMAKE_INSTALL_PREFIX=$PREFIX

但是 make install 尝试将一些程序文件放入 /usr/local/share 中，这不是我想要的位置:

> make install
[  3%] Built target generated_sources
[  6%] Built target test-gravity
[  9%] Built target lgi-check
[  9%] Built target version_stamp
[ 29%] Built target generated_icons
[ 31%] Checking for LGI...
Building for Lua 5.3.
Found lgi 0.9.2.
[ 31%] Built target lgi-check-run
[ 35%] Built target generate_awesomerc
[100%] Built target awesome
Install the project...
-- Install configuration: ""
-- Up-to-date: /home/user/.local/bin/awesome
-- Up-to-date: /home/user/.local/bin/awesome-client
-- Installing: /usr/local/share/awesome/lib
CMake Error at cmake_install.cmake:69 (file):
  file INSTALL cannot make directory "/usr/local/share/awesome/lib": No such
  file or directory


make: *** [Makefile:107: install] Error 1

是否有一些类似于 CMAKE_INSTALL_PREFIX 或 CMAKE_INSTALL_LIBDIR 的 cmake 变量需要为共享数据指定？

Answer 1

使用 cmake 模块时，您将拥有用于共享的CMAKE_INSTALL_DATADIR:include( GNUInstallDirs )

注意:使用cmake --build build --target install -- DESTDIR=foo时 请阅读 CMAKE_INSTALL_PREFIX 文档

On UNIX one can use the DESTDIR mechanism in order to relocate the whole installation. DESTDIR means DESTination DIRectory.

WARNING: DESTDIR may not be used on Windows because installation prefix usually contains a drive letter like in C:/Program Files which cannot be prepended with some other prefix.
