* #11371 Remove GLEW dependency and use Qt's QOpenGLFunctions Replace embedded GLEW library with Qt's native OpenGL function loading (QOpenGLFunctions/QOpenGLExtraFunctions) to resolve Qt 6 compatibility warnings about GLEW conflicts with qopenglfunctions.h. - Update CVF_CALLSITE_OPENGL macro to provide QOpenGLExtraFunctions pointer - Replace GLEW initialization with Qt OpenGL context validation - Keep direct calls for fixed-function GL (glBegin, glEnd, glMatrixMode, etc.) - Remove glew/ directory containing embedded GLEW source * #11371 Remove GLU dependency to fix Windows build error GL/glu.h conflicts with Qt's OpenGL headers on Windows due to APIENTRY redefinition. Replace gluBuild2DMipmaps with glTexImage2D + glGenerateMipmap, and gluOrtho2D with glOrtho.
