无法找到boost_process cmake find_package。

I'm trying to import boost libraries into my C++ project, and for some reason it cannot find Boost.Process, although it finds the others.

我正在尝试将boost库导入到c++项目中，出于某种原因，它无法找到boost。过程，尽管它找到了其他的。

My CMakeLists.txt file:

我的CMakeLists。txt文件:

cmake_minimum_required(VERSION 3.9 FATAL_ERROR)
set (PROJECT_NAME "test-stuff" CXX)
project (${PROJECT_NAME})

set(Boost_USE_MULTITHREADED ON)

find_package(Boost 1.64.0 REQUIRED system filesystem process)

if(Boost_FOUND)
  include_directories (SYSTEM ${Boost_INCLUDE_DIR})
endif()

include_directories(include)

file(GLOB SOURCES "src/*.cpp")

add_executable(${PROJECT_NAME} ${SOURCES})

target_link_libraries (${PROJECT_NAME} ${Boost_LIBRARIES})

  Unable to find the requested Boost libraries.

  Boost version: 1.64.0

  Boost include path: /usr/local/include

  Could not find the following Boost libraries:

          boost_process

  Some (but not all) of the required Boost libraries were found.  You may
  need to install these additional Boost libraries.  Alternatively, set
  BOOST_LIBRARYDIR to the directory containing Boost libraries or BOOST_ROOT
  to the location of Boost.

I know Boost.Process was only included in Boost 1.64 and up, but according to the output I'm using Boost 1.64, and Cmake 3.9. I looked in /usr/local/include/boost and process.hpp was there.

我知道提振。进程只包含在Boost 1.64和up中，但是根据输出，我使用Boost 1.64，而Cmake 3.9。我查看了/usr/local/include/boost和process。高压泵。

Thanks for any advice.

谢谢你的任何建议。

So, after hours of banging my head against the wall, I realized I didn't need to import Boost.Process with find_package since it's a header-only library (argggg). I removed the "process" import in CMakeList.txt and ta-dah: it worked.

所以，在数小时的碰壁之后，我意识到我不需要增加进口。使用find_package的过程，因为它是一个header-only库(argggg)。我删除了CMakeList中的“流程”导入。txt和哒哒:成功了。
