Qt creator Adding external library (still: Cannot open include file: 'GL/glew.h')

I followed the instruction:

  1. In the Projects pane, open the project file (.pro).
  2. Right-click in the code editor to open the context menu and select Add Library....

Add Library

Then the following lines were added into the pro file:

win32:CONFIG(release, debug|release): LIBS += -L$$PWD/D:/OpenGL/glew-1.5.4/lib/ -lglew32
else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/D:/OpenGL/glew-1.5.4/lib/ -lglew32d

INCLUDEPATH += $$PWD/D:/OpenGL/glew-1.5.4/include
DEPENDPATH += $$PWD/D:/OpenGL/glew-1.5.4/include

However, I click the green triangle icon on the bottom left the run the program, still get the errors:

error: C1083: Cannot open include file: 'GL/glew.h': No such file or directory

  1. Open .pro file with Editor
  2. Add directory of library in INCLUDEPATH += section

 Append ` \` at the end of library path
  1. Go to Build > Run qmake

  1. Check if library has been included .

I had the same problem and I figured it out just now: You have to run qmake(build->run qmake) to validate changes in the pro file.

Check if the desired files really exist under D:/OpenGL/glew-1.5.4/include. I.e. is there a folder named GL and inside it a file named glew.h?

Then try to remove the $$PWD/ part from the paths.

If this doesn't help replace the generated lines with just those two lines:

LIBS += -L$$quote(D:/OpenGL/glew-1.5.4/lib/) -lglew32
INCLUDEPATH += $$quote(D:/OpenGL/glew-1.5.4/include)

INCLUDEPATH += D:/OpenGL/glew-1.5.4/include
LIBS += -Lc:D:/OpenGL/glew-1.5.4/lib -lname

Just add the above line in the .pro file.Then check it.
