ctime Error when including boost::filesystem - c++

Question

I am working on small project. The essential part is, that a video should be captured, saved and moved to another folder.
For the video part I am using FFmpeg this works without any problems. To safe information I am using tinyXML2. For copying and moving of the video files I like to use boost.
At the moment I am working on windows, and I am using CMake.
The problem is, that in the moment I include the "boost/filesystem" the compiler starts failing. After the use of google and analyzing the error messages I think that there is a problem with headers <ctime> or <time>. The file that is using <ctime> is xmltest that is passed by tinyxml2.
But to be honest I am very much clueless how and why this happens.
I already tried to switch the order of the includes as mentioned here.
I tried to exclude the file that uses ctime, but this is not possible.
I tried to work around the problem, so I don't have to use Boost, but this is hard due to the platform independency.
The log file:

The way I include Boost & tinyxml:
find_package(TinyXML2)
find_package(Boost COMPONENTS filesystem system REQUIRED)
...
add_executable(programm ${project_sources}
${project_headers}
${TINYXML_INC})
target_link_libraries(programm PUBLIC
Boost::filesystem
Boost::system
${TinyXML2_LIBRARIES})
target_include_directories(programm PRIVATE
${Boost_INCLUDE_DIRS}
${Boost_LIBRARY_DIRS}
${TinyXML2_INCLUDE_DIR})
target_link_directories(programm PUBLIC
${Boost_INCLUDE_DIRS}
${Boost_LIBRARY_DIRS}
${TinyXML2_INCLUDE_DIR})
The include of Boost in Util.h:
#include <string>
#include <boost/filesystem.hpp>
namespace util {
bool existens_file(std::string* path);
int existens_directory(std::string* path);
bool create_directory(std::string* path);
}
Part in xmltest where <ctime> is used:
#include "tinyxml2.h"
#include <cerrno>
#include <cstdlib>
#include <cstring>
#include <ctime>
...
XMLDocument* doc = new XMLDocument();
clock_t startTime = clock();
doc->LoadFile( argv[1] );
clock_t loadTime = clock();
int errorID = doc->ErrorID();
delete doc; doc = 0;
clock_t deleteTime = clock();
EDIT
After some Testing I tried to use <ctime> in diffrent files without the include of boost. In this case I also receive the same problems as mentioned above.

Answer 1

So I fixed the issue, in the ffmpeg-library is file that is called time.h or Time.h.
The misstake was that accidentally linked the directory that contained this file.
I don't know why but with the include of boost::filesystem this was triggered and the time-file of ffmpeg was used.
I resolved this problem, through removing the linked directory of ffmpeg.
