第一种方式，cuda使用find_package：
cmake_minimum_required(VERSION 3.9) project(untitled1) find_package(CUDA REQUIRED) message("CUDA_TOOLKIT_ROOT_DIR: ${CUDA_TOOLKIT_ROOT_DIR}") message("cuda version: ${CUDA_VERSION_STRING}") include_directories( ${CUDA_INCLUDE_DIRS} ${CUDA_TOOLKIT_ROOT_DIR}/samples/common/inc ) set(CMAKE_CUDA_FLAGS "${CMAKE_CUDA_FLAGS} -std=c++11 -gencode arch=compute_61,code=sm_61 -DNDEBUG") message("CMAKE_CUDA_FLAGS: ${CMAKE_CUDA_FLAGS}") set(CMAKE_AUTOMOC ON) set(CMAKE_AUTOUIC ON) set(CMAKE_AUTORCC ON) set(CMAKE_INCLUDE_CURRENT_DIR ON) set(QT_DIR "/opt/Qt5.12.0") set(QT_SUB_DIR "5.12.0") find_package(Qt5 COMPONENTS Widgets Gui OpenGL HINTS ${QT_DIR}/${QT_SUB_DIR}/gcc_64/lib/cmake/Qt5) set(CMAKE_CXX_STANDARD 11) set(INCLUDE_FILES ) set(SOURCE_FILES main.cpp main_test.cu ) CUDA_ADD_EXECUTABLE(untitled1 ${SOURCE_FILES} ${INCLUDE_FILES}) target_link_libraries(untitled1 Qt5::Widgets ${CUDA_LIBRARIES} ${CUDA_cudadevrt_LIBRARY} )第二种方式，使用cmake的CUDA language：
cmake_minimum_required(VERSION 3.9) project(untitled CUDA CXX) include_directories( /usr/local/cuda/samples/common/inc /usr/local/cuda/include ) set(CMAKE_CUDA_FLAGS "${CMAKE_CUDA_FLAGS} -gencode arch=compute_61,code=sm_61") message("CMAKE_CUDA_FLAGS: ${CMAKE_CUDA_FLAGS}") set(CMAKE_CXX_STANDARD 11) set(CMAKE_AUTOMOC ON) set(CMAKE_AUTOUIC ON) set(CMAKE_AUTORCC ON) set(CMAKE_INCLUDE_CURRENT_DIR ON) set(QT_DIR "/opt/Qt5.12.0") set(QT_SUB_DIR "5.12.0") find_package(Qt5 COMPONENTS Core HINTS ${QT_DIR}/${QT_SUB_DIR}/gcc_64/lib/cmake/Qt5) set(INCLUDE_FILES ) set(SOURCE_FILES main.cpp main_test.cu ) if ( TARGET Qt5::Core ) get_property( core_options TARGET Qt5::Core PROPERTY INTERFACE_COMPILE_OPTIONS ) string( REPLACE "-fPIC" "" new_core_options "${core_options}" ) set_property( TARGET Qt5::Core PROPERTY INTERFACE_COMPILE_OPTIONS ${new_core_options} ) set_property( TARGET Qt5::Core PROPERTY INTERFACE_POSITION_INDEPENDENT_CODE "ON" ) set( CMAKE_CXX_COMPILE_OPTIONS_PIE "-fPIC" ) endif() add_executable(untitled ${SOURCE_FILES} ${INCLUDE_FILES}) target_link_libraries(untitled Qt5::Core )第二种方式要处理编译选项传入问题（nvcc fatal : Unknown option 'fPIC'）。
