我正在从事一个依赖于 Boost 的大型 C++ 项目。该项目是在使用 CMake 的各种平台上构建的。在我的 Windows 机器上，我使用的是 CMake 2.8.9、Visual Studio 2010 和 Boost 1.50.0(从源代码构建)。
多年来，我一直在毫无问题地一起使用 CMake 和 Boost，Boost 版本最早是 1.33。 现在，CMake 突然找不到 Boost 库。我的机器上唯一发生变化的是我最近安装了 Visual Studio 2012，但我认为这与问题无关(另一方面，据我所知，这是 只有发生了变化)。
这是我用来调用 CMake 的命令行:
cmake ..\src -DBOOST_ROOT=..\..\boost -DQT_QMAKE_EXECUTABLE=..\..\qt-4.8.0\bin\qmake.exe
这曾经完美地工作，但现在输出:

显然，它确实找到了我的 Boost 安装，因为它报告了正确的路径和版本号。

正如我们所见，Boost 是使用多线程运行时使用 Visual Studio 2010 (vc100) 构建为静态库的。

我也曾尝试指定 BOOST_LIBRARYDIR 而不是 BOOST_ROOT，但无济于事。
同样，这多年来一直在 Windows、Linux 和 Mac OS X 的许多变体上完美运行。我正在寻找它突然停止运行的原因。
最佳答案
在您的调试输出中，它看起来像 Boost_USE_STATIC_LIBS 未设置，但您正在寻找静态 boost 库。
尝试再次运行 CMake，但将 -DBoost_USE_STATIC_LIBS=ON 添加到命令中。
事实上，你的CMakeLists.txt wraps this in another variable USE_STATIC_BOOST .将其设置为 ON 应该具有相同的效果。
关于c++ - CMake 不再查找静态 Boost 库，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/12020736/
