Atom libs not recognized

Hi there
i have a rather general problem. All libs are not recognized. It does not mater if i install them to global installation, local installation as well as copying the files to a folder inside lib like lib/DHT/DHT_U.h

The error is: fatal error: DHT.h: No such file or directory

I searched around and found many threads that lead to python.
my $python --version is Python 3.6.4
and the pip --version is pip 9.0.2 from /usr/local/lib/python3.6/site-packages (python 3.6)
its installed useing homebrew on a macOS 10.13.3 High Sierra system.
platformio Home 0.9.0┬ĚCore 3.5.3a4

whats wrong with my system?
