I've downloaded the latest master source files and after configuring and generating the solution file from cmake. I get several Lnk2005 errors: 16>window_w32.obj : error LNK2005: _cvCreateTrackbar already defined in window.obj 16>window_w32.obj : error LNK2005: _cvCreateTrackbar2 already defined in window.obj 16>window_w32.obj : error LNK2005: _cvDestroyAllWindows already defined in window.obj 16>window_w32.obj : error LNK2005: _cvDestroyWindow already defined in window.obj 16>window_w32.obj : error LNK2005: _cvGetTrackbarPos already defined in window.obj 16>window_w32.obj : error LNK2005: _cvGetWindowHandle already defined in window.obj 16>window_w32.obj : error LNK2005: _cvGetWindowName already defined in window.obj 16>window_w32.obj : error LNK2005: _cvInitSystem already defined in window.obj 16>window_w32.obj : error LNK2005: _cvMoveWindow already defined in window.obj 16>window_w32.obj : error LNK2005: _cvNamedWindow already defined in window.obj 16>window_w32.obj : error LNK2005: _cvResizeWindow already defined in window.obj 16>window_w32.obj : error LNK2005: _cvSetMouseCallback already defined in window.obj 16>window_w32.obj : error LNK2005: _cvSetTrackbarPos already defined in window.obj 16>window_w32.obj : error LNK2005: _cvShowImage already defined in window.obj 16>window_w32.obj : error LNK2005: _cvStartWindowThread already defined in window.obj 16>window_w32.obj : error LNK2005: _cvWaitKey already defined in window.obj 16> Creating library E:/opencv-working/build_x86/lib/Debug/opencv_highgui300d.lib and object E:/opencv-working/build_x86/lib/Debug/opencv_highgui300d.exp 16>E:\opencv-working\build_x86\bin\Debug\opencv_highgui300d.dll : fatal error LNK1169: one or more multiply defined symbols found
