我正在尝试使用 CMake 针对 conda 环境构建一些项目（ crocoddyl ）。构建命令是：

cmake -DCMAKE_INSTALL_PREFIX=$CONDA_PREFIX ${CMAKE_ARGS} -S . -B build

我有所有必要的依赖项，即 pinocchio、libboost-python-devel、eignepy。 CMake 成功找到 eignepy，这很好，但是，当 eigenpy 检查 boost-python 依赖项时，一切都会崩溃并出现错误：

CMake Error at /home/m8/micromamba/envs/sber-croc/share/cmake-3.29/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
  Could NOT find Boost (missing: python310) (found version "1.85.0")
Call Stack (most recent call first):
  /home/m8/micromamba/envs/sber-croc/share/cmake-3.29/Modules/FindPackageHandleStandardArgs.cmake:600 (_FPHSA_FAILURE_MESSAGE)
  /home/m8/micromamba/envs/sber-croc/share/cmake-3.29/Modules/FindBoost.cmake:2393 (find_package_handle_standard_args)

  /home/m8/micromamba/envs/sber-croc/lib/cmake/eigenpy/eigenpyConfig.cmake:149 (SEARCH_FOR_BOOST_PYTHON)
  cmake/package-config.cmake:110 (find_package)
  CMakeLists.txt:90 (add_project_dependency)

我肯定知道，其中$CONDA_PREFIX/lib包含libboost_python310.so和libboost_python310.so.1.84.0。但是我的主机系统没有 python 绑定，只有 1.85.0 版本的 boost。所以我认为在 CMake 期间，eigenpy 的 find_package 会混淆前缀并查找错误的 lib 目录。

如何忽略系统库或正确指定前缀？

export CMAKE_PREFIX_PATH=$CONDA_PREFIX我也尝试过，但-DCMAKE_PREFIX_PATH=$CONDA_PREFIX没有运气。导出LD_LIBRARY_PATH也没有效果。 CMake、编译器、pkg-config，一切都安装在 conda 环境中。

假设我使用了 find_package(SDL REQUIRED)，现在我需要通过 target_link_libraries 链接到该库，要传递给 target_link_libraries 的变量名称是什么？一般来说，除了启发式猜测之外，还有其他方法可以找到这些变量吗？我尝试过 SDL_LIBRARY、SDL2_LIBRARY 和 SDL_LIBRARIES。我确实安装了 sdl2。

我本以为这会起作用，但它没有：

cmake_minimum_required(VERSION 3.10)
project(someProject)

# Find SDL2
find_package(SDL REQUIRED)
find_package(SDL_image REQUIRED)

# Include directories
include_directories(${SDL2_INCLUDE_DIRS} ${SDL2_IMAGE_INCLUDE_DIRS})

# Set source files
set(SOURCES main.cpp)

# Set executable
add_executable(someProject ${SOURCES})

# Link libraries
target_link_libraries(someProject ${SDL2_LIBRARIES} ${SDL2_IMAGE_LIBRARIES})

请记住，在从源代码构建方面我是初学者（尝试了几次，几乎总是失败）。

我正在尝试为运行 Ubuntu 19 的 Raspberry Pi 3b 构建 MySQL 连接器/C++ 8。我按照官方说明安装了所有先决条件（不是 100% 确定是否codecvt_utf8存在）。

我正在构建没有 JDBC 和 BOOST。我已经从源代码构建了 OpenSSL 1.1.1。

我正在运行的命令（我--target install直接添加了 - 不确定这是否是一个问题）：

cmake .
cmake --build . --target install --config Release

由于以下原因，它失败了 AFAIK：

CMakeFiles/CMakeTmp/CheckIncludeFile.c:1:10：致命错误：sys/endian.h：没有这样的文件或目录

CMakeFiles/CMakeTmp/CheckIncludeFile.c:1:10：致命错误：sys/byteorder.h：没有这样的文件或目录

我查过了/usr/include，没有目录sys。endian.h直接在顶层，根本byteorder.h不存在。

为什么有些文件不见了？

如前所述，该sys目录位于 Ubuntu 上的不同位置。所以我运行了这个：

ln -s /usr/include/aarch64-linux-gnu/sys /usr/include/sys

但是丢失的文件实际上也不在该目录中。

跑步

find /usr/include -type f -name endian.h
find /usr/include -type f -name byteorder.h

显示，文件实际上在/usr/include/aarch64-linux-gnu/bits/endian.hand中/usr/include/aarch64-linux-gnu/asm/byteorder.h，我应该链接那些吗？似乎是个坏主意。

我正在使用 CentOS 7。

我访问了 gdcm 源代码页面，唯一有链接的 Linux 发行版是 Debian 和 Ubuntu。我下载并解压缩了 GDCM-$VERSION-Linux.tar.gz。然后我阅读了 INSTALL.txt。它提供了以下安装 gdcm 的说明。

 * git clone --branch release git://git.code.sf.net/p/gdcm/gdcm
 * mkdir gdcmbin
 * cd gdcmbin
 * ccmake ../gdcm
   [select your configuration]
 * Press 'c' (configure), Press 'g' (generate)
 * make

当我尝试 ccmake ../gdcm 并按下“c”时，我得到了

CMake Error at CMakeLists.txt:1 (cmake_minimum_required):
  CMake 3.9.2 or higher is required.  You are running version 2.8.12.2

然后我尝试了

sudo yum install cmake

并得到

Nothing to do

我正在尝试为基于 ARM 的笔记本电脑编译 Paraview 图形可视化软件；但是，我收到了一些似乎与 cmake 'policies' 相关的配置警告。警告文本和 cmake 手册页表明我应该能够运行该命令cmake_policy()来设置特定策略；但是，我不知道如何或在哪里运行它。

如何设置特定的 cmake 策略？

我正在尝试使用带有 mingw 交叉编译器的 cmake 从 debian 创建一个 *.deb 文件。CMake 的编译器测试在使用dpkg-buildpackage.

正常建设是好的：

完整日志中有趣的部分是链接失败：

/usr/bin/i686-w64-mingw32-ld: unrecognized option '-z'

mingw 链接器无法识别该-z选项。当我diffCMakeCache.txt 时，我可以看到 dpkg-buildpakcage 默认添加了一些链接器标志：

< CMAKE_EXE_LINKER_FLAGS:STRING=-Wl,-z,relro
---
> CMAKE_EXE_LINKER_FLAGS:STRING=

我怎样才能防止dpkg-buildpackage这样做？

仅供参考：我的debian/rules文件如下所示：

假设我有我的源/目录，我像这样从我的主文件夹运行 cmake

~]$ cmake /path/to/my/sources/sources

然后我进行安装

~]$ make install

完成后，我意识到这是一个不好的做法，并决定按照教程创建一个二进制文件夹以运行 cmake并从那里执行make install命令，以便将二进制文件放在它自己的文件夹中，而不是弄乱我的主目录：binaries]$ cmake ../sources

然后我进入二进制文件并再次make install从那里运行。这怎么弄乱我的系统？我没有正确卸载我的软件（也没有运行 make clean 也没有执行手动步骤），而是从两个不同的位置运行了两次 make install 实用程序。我很好奇这种做法是如何影响系统的。Maybie 它只是在我的 linux 安装中覆盖了一些目录和配置，但我不确定。

谢谢你们

我试图通过以下方式解决此问题：

  1. 用于 cmake --build . --target clean删除构建的文件并cmake --build .再次运行。

  2. 按照上面给出的说明，将目录更改为 lib，然后运行ranlib libLLVMSupport.a​​.

但这些都不起作用：我又跑cmake --build .了，他们给了：

make[1]: *** [utils/TableGen/CMakeFiles/llvm-tblgen.dir/all] Error 2
Makefile:149: recipe for target 'all' failed
make: *** [all] Error 2

我在方法2中检查了lib/libLLVMSupport.a的时间戳，发现它没有改变，意味着它不是由cmake --build ..

如何解决这个问题？
