CMake的升压1.59.0几何 [英] CMake Boost 1.59.0 geometry

问题描述

我是相当新的与C ++一起使用boost。我刚安装升压1.59.0，我想使用的几何库。

I am fairly new to using boost along with C++. I have just installed Boost 1.59.0 and I want to use the geometry library.

如果我包括 FIND_PACKAGE（升压1.47必填）发现振奋，没有问题就出现了。如果我再包括 FIND_PACKAGE（升压1.47组件几何必填）我收到以下错误：

If I include FIND_PACKAGE( Boost 1.47 REQUIRED ) it finds boost and no problems arises. If I then include FIND_PACKAGE( Boost 1.47 COMPONENTS geometry REQUIRED ) I get the following error:

 Unable to find the requested Boost libraries.

  Boost version: 1.59.0

  Boost include path: /usr/include

  Could not find the following Boost libraries:

          boost_geometry

  No Boost libraries were found.  You may need to set BOOST_LIBRARYDIR to the
  directory containing Boost libraries or BOOST_ROOT to the location of
  Boost.

如果我运行下面的 [-f /usr/include/boost/geometry/geometry.hpp＆功放;＆安培;回声找到||回声在CLI我得到找到结果未找到。如此看来，它的存在，但CMake的告诉我，事实并非如此。

If I run the following [ -f /usr/include/boost/geometry/geometry.hpp ] && echo "Found" || echo "Not found" in the CLI I get Found as a result. So it seems that it's there, but CMake tells me it's not.

我是什么误会？

推荐答案

组件只用于建库。几何所以它不是需要一个只有头库。你只需要找到升压头位置。

COMPONENTS is required only for built libraries. Geometry is an header-only library so it's not needed. You need only to find the boost headers location.
