我正在尝试安装具有Boost依赖关系的特定c ++库。我安装Boost没问题，包含路径在/ usr / local / include /.
下然而，当我调用cmake时，我收到以下错误：
CMake Error at
/usr/local/Cellar/cmake/3.3.2/share/cmake/Modules/FindBoost.cmake:1245 (message):
Unable to find the requested Boost libraries.
Boost version: 0.0.0
Boost include path: /usr/include
Detected version of Boost is too old. Requested version was 1.36 (or newer).
Call Stack (most recent call first):
CMakeLists.txt:10 (FIND_PACKAGE)
我知道Boost包含路径不匹配，但我不知道如何让它引用正确的路径。 CMakeLists.txt文件调用FIND_PACKAGE（Boost 1.36 COMPONENTS program_options REQUIRED）：我没有看到任何允许我指定路径的参数。
谢谢，
答案 0 :(得分：0)
您可以使用以下方式设置Boost路径：

确保在CMakeLists.txt中的FIND_PACKAGE调用之前放置它。 （Cmake doesn't find Boost）
