Cmake 中调用Qt库

cmake_minimum_required(VERSION 3.8.2) project(demo) set(CMAKE_CXX_STANDARD 11) # Find includes in corresponding build directories set(CMAKE_INCLUDE_CURRENT_DIR ON) # Instruct CMake to run moc automatically when needed. set(CMAKE_AUTOMOC ON) include_directories(include /home/hhit/lib/ffmpeg-release/include) link_directories(lib /home/hhit/lib/ffmpeg-release/lib) # Find the QtWidgets library find_package(Qt5Widgets) # Tell CMake to create the helloworld executable add_executable(demo hhvideoalarm.cpp hhvideostream.cpp hhvideowidget.cpp main.cpp widget.cpp) # Use the Widgets module from Qt 5. target_link_libraries(demo Qt5::Widgets hhclient avcodec avformat swscale avdevice avfilter avutil swresample)

Cmake 中调用SDL2

INCLUDE_DIRECTORIES(/Library/Frameworks/SDL2.framework/Headers/ /Library/Frameworks/SDL2_image.framework/Headers/) ....... TARGET_LINK_LIBRARIES(untitled5 ${SDL2_LIBRARIES} ${SDL2IMAGE_LIBRARY})

Cmake中调用ffmpeg

INCLUDE_DIRECTORIES(/usr/local/Cellar/ffmpeg/3.3.2/include) link_directories(/usr/local/Cellar/ffmpeg/3.3.2/lib) LINK_LIBRARIES( libavcodec.a libavfilter.a libavresample.a libpostproc.a libswscale.a libavdevice.a libavformat.a libavutil.a libswresample.a )

Cmake中调用opencv3

安装opencv

编译环境安装： sudo apt-get install build-essential 必需包安装： sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev 可选包安装： sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev 编译 cmake -D CMAKE_INSTALL_PREFIX=/usr/local/opencv-3.1.0 -D BUILD_TIFF=ON -D WITH_FFMPEG=ON .. make

调用

set(OpenCV_DIR /usr/local/Cellar/opencv3/3.2.0/share/OpenCV) find_package( OpenCV REQUIRED ) ...... target_link_libraries( untitled5 ${OpenCV_LIBS})
