BSP_TS_Init and StemWin ..
To solve correctly this problem, you should (for all include directories in “Project” >> Properties >> C/C++ General >> Paths and Symbols) replace the first ‘..’ by ’${ProjDirPath}’; then all include directives will be absolute and no more relative, thus will work for all source files...
To simplify, you could do this by a global substitute in the .cproject file, but you should first close the project and then reopen it afterwards (by precaution, keep a copy of the original file).
Please write it carefully. Both cases.
