what I'm trying to do is as you can guess from the title to link Boost libraries through CMake (I'm working with CLion to write cross platform code, so I have no other chance). I am sure I built everything correctly cause when I use it inside Visual Studio it works with no problem at all. Here's my CMake code:
cmake_minimum_required(VERSION 3.7)
project(BoostHello)
set(BOOST_ROOT C:/boost_1.63.0)
find_package(BOOST 1.6.0 REQUIRED)
include_directories( ${Boost_INCLUDE_DIR} )
set(CMAKE_CXX_STANDARD 14)
set(SOURCE_FILES main.cpp)
add_executable(BoostHello ${SOURCE_FILES})
target_link_libraries( BoostHello ${Boost_LIBRARIES} )
And here are my compilation errors:
"C:\Program Files (x86)\JetBrains\CLion 2017.1\bin\cmake\bin\cmake.exe" --build C:\Users\Admin\CLionProjects\BoostHello\cmake-build-debug --target all -- -j 8

And eventually here's the code I'm trying to compile:
#include <iostream>
#include <boost/filesystem.hpp>
int main(int argc, char** argv) {
boost::filesystem::path myPath = {L"C:/Users/Admin/ClionProjects/BoostHello"};
std::cout << "Root:\t" << myPath.root_path() << std::endl;
std::cout << "Relative:\t" << myPath.relative_path() << std::endl;
std::cout << "Filename:\t" << myPath.filename() << std::endl;
return 0;
}
What am I doing wrong? I am compiling with MinGW. Thanks in advance!
