| 2013-12-24 06:55:52 -0600 | asked a question | opencv_ffmpeg243 library file Hi in the staticlib folder there is a dll file called "opencv_ffmpeg243.dll" . there is no lib file (opencv_ffmpeg243.lib) for that . So after making my project with static libraries this dll (opencv_ffmpeg243.dll) should exit. Is it possible to add this library statically too. |
