【问题描述】：

我想使用 CGAL 库，我正在使用： CGAL 4.10 ,Microsoft Visual Studio 2013 , CMake 3.9.3 , boost 1.65, QT creator 4.3.1

使用 Cmake 配置 CGAL 时，显示以下错误：

Looking for pthread.h

CMake Error at C:/Program Files/CMake/share/cmake-3.9/Modules/FindBoost.cmake:1902 (message):

CMake Error: The following variables are used in this project, but they     are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the  CMake files:
Boost_INCLUDE_DIR (ADVANCED)
used as include directory in directory C:/dev/CGAL-4.10/src/CGAL
used as include directory in directory C:/dev/CGAL-4.10/src/CGAL
used as include directory in directory C:/dev/CGAL-4.10/src/CGAL_Core
used as include directory in directory C:/dev/CGAL-4.10/src/CGAL_Core
used as include directory in directory C:/dev/CGAL-4.10/src/CGAL_ImageIO
used as include directory in directory C:/dev/CGAL-4.10/src/CGAL_ImageIO

我将 Boost_INCLUDE_DIR,BOOST_ROOT 手动添加到环境变量中

Boost_INCLUDE_DIR=C:\dev\boost_1_65_0;BOOST_ROOT=C:\dev\boost_1_65_0

我用visual sutudio 2015、2013尝试了许多版本的boost、cmake和cgal，但都没有工作

感谢您的帮助。谢谢

【问题讨论】：

错误信息告诉你设置BOOST_INCLUDEDIR，而不是Boost_INCLUDE_DIR
我尝试了您的解决方案，它显示相同的错误：无法找到 Boost 头文件。请将 BOOST_ROOT 设置为包含 Boost 的根目录或 BOOST_INCLUDEDIR 设置为包含 Boost 标头的目录。
C:\dev\boost_1_65_0的内容是什么？
Boost 包（boost、doc、libs、status、tools、更多）文件夹
我建议你安装 boost 这样你就只有<prefix>/include 和<prefix>/lib。这样CMake更容易找到它，然后只需要设置BOOST_ROOT即可。

【解决方案1】：

如果你使用的是 Cygwin，你可以使用 cmake-gui 并使用界面来填充你的路径，这限制了拼写错误的风险，并且更容易找到丢失的字段。另一种选择是在构建目录中编辑 hte CMakeCache.txt 以提供路径，因此您不必将变量声明为环境变量。
