Trouble with my.prf [Not found headers]

[A Former User]

I create my.prf:
@INCLUDEPATH += $$PRO_FILE_PWD/inc #there is my included headers is located@

my.prf located at project dir $$_PRO_FILE_PWD

And I add string to the project:
@CONFIG+=my@

I'm getting an error:
@error: someinc.h: No such file or directory
#include "someinc.h"@

I also try set clear path:
@INCLUDEPATH += /home/myhome/project/inc #there is my included headers is located@
I get the same error.
What am I doing wrong?
