我正在尝试将 boost 库导入到我的 C++ 项目中，由于某种原因它找不到 Boost.Process，尽管它找到了其他库。

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})

错误的完整跟踪（带有调试设置）：

  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.
Call Stack (most recent call first):
  CMakeLists.txt:19 (find_package)

我知道 Boost.Process 仅包含在 Boost 1.64 及更高版本中，但根据输出我使用的是 Boost 1.64 和 Cmake 3.9。我查看了 /usr/local/include/boost 并且 process.hpp 在那里。

感谢您的任何建议。

因此，经过数小时的头撞墙后，我意识到我不需要使用 find_package 导入 Boost.Process，因为它是一个仅包含标头的库 (argggg)。我删除了 CMakeList.txt 和 ta-dah 中的“进程”导入：它起作用了。
