Are you using PSoC Creator4.1 Update1
I a nightmare to get it to work with external libraries.
I tried using the build option and specified directories and files—didn’t work.
Tried to drag and drop files into the directory—didn’t work.
The only things that worked was creating new files and cutting and pasting content into the newly created file.
Your system is very, very, very awkward to use with external libraries.
