Hello, so i am trying to add the boost library to my qt project but i get this error

Cannot open include file: 'boost/filesystem.hpp': No such file or directory


here is my qt project variables:

LIBS += \
"-L$$_PRO_FILE_PWD_/3rdparty/libs/boost_1_58_0/lib32-msvc-12.0"
INCLUDEPATH += \
$$_PRO_FILE_PWD_/3rdparty/libs/boost_1_58_0

I looked this up and a lot of them were saying the libraries were in the


boost_1_58_0/stage/lib

but i do not have those directory's, i found some libraries in the

boost_1_58_0/lib32-msvc-12.0

folder. Another thing that is throwing me off is the autocomplete is suggesting the

boost/filesystem.hpp


file when i want to include it. Can someone please help me with this error and problem?
