E0145 成员可能未初始化 - cmake - VS2017

我正在尝试将 C++ 应用程序与 PCL 库链接。我使用 VCPKG 安装了 PCL 及其所有依赖项。我正在使用 Visual Studio 2017 和 cmake 3.12 for X64。当我尝试构建解决方案时，它给了我以下错误。

E0145   member "boost::filesystem::path::separator" may not be initialized 
C:\vcpkg-pcl\vcpkg-master\installed\x64- 
windows\include\boost\filesystem\path.hpp   65  

E0145   member "boost::filesystem::path::preferred_separator" may not be 
initialized C:\vcpkg-pcl\vcpkg-master\installed\x64- 
windows\include\boost\filesystem\path.hpp   66  

E0145   member "boost::filesystem::path::dot" may not be initialized 
C:\vcpkg-pcl\vcpkg-master\installed\x64- 
windows\include\boost\filesystem\path.hpp   67  

E2512   the argument to a feature-test macro must be a simple identifier 
C:\vcpkg-pcl\vcpkg-master\installed\x64- 
windows\include\boost\system\error_code.hpp 401

在控制台上，我发现此错误，尽管我使用 VCPKG 安装了 Pthreads 库并设置了 PTHREADS_INCLUDE 变量

-- Looking for pthread.h - not found

这是我的 CMakelists.txt 文件

cmake_minimum_required(VERSION 2.8 FATAL_ERROR)

project(compute_parameters)
find_package(PCL 1.5 REQUIRED)
SET(PTHREADS_INCLUDE "${PTHREADS_ROOT}/include")
find_path (PTHREADS_INCLUDE "pthread.h" NO_CMAKE_FIND_ROOT_PATH)

include_directories(${PCL_INCLUDE_DIRS};${PTHREADS_INCLUDE})
link_directories(${PCL_LIBRARY_DIRS})
add_definitions(${PCL_DEFINITIONS})

add_executable (compute_parameters compute_parameters.cpp)
target_link_libraries (compute_parameters ${PCL_LIBRARIES})

任何帮助将不胜感激。
