_mkdir(ROOT_DIR "/data/");

if (NOT ROOT_DIR_DEFINED)
? ? add_definitions(-DROOT_DIR="${PROJECT_SOURCE_DIR}")

多個源文件工程編譯

cmake_minimum_required(VERSION 3.5)project(ssca)set(CMAKE_CXX_STANDARD 14)set(WINDOWS TRUE CACHE INTERNAL "") set(PLATFORM_PREFIX "win64" CACHE INTERNAL "") set_property(GLOBAL PROPERTY USE_FOLDERS ON)set(OpenCV_STATIC ON) set(OpenCV_DIR D:/thirdparty/build/install/win64)find_package(OpenCV REQUIRED)FILE(GLOB_RECURSE src_SRC_LIST "src/*.cpp src/*.h") FILE(GLOB_RECURSE CAFilter_SRC_LIST "CAFilter/*.cpp CAFilter/*.h") FILE(GLOB_RECURSE CANLC_SRC_LIST "CANLC/*.cpp CANLC/*.h") FILE(GLOB_RECURSE CAST_SRC_LIST "CAST/*.cpp CAST/*.h") FILE(GLOB_RECURSE CC_SRC_LIST "CC/*.cpp CC/*.h") FILE(GLOB_RECURSE PPSG_SRC_LIST "PPSG/*.cpp PSG/*.h") FILE(GLOB_RECURSE PPWM_SRC_LIST "PPWM/*.cpp PPWM/*.h")add_executable(ssca main.cpp ${src_SRC_LIST} ${CAFilter_SRC_LIST} ${CANLC_SRC_LIST} ${CAST_SRC_LIST} ${CC_SRC_LIST} ${PPSG_SRC_LIST} ${PPWM_SRC_LIST}) target_link_libraries(ssca ${OpenCV_LIBS})

3.多個編譯子文件家?

add_subdirectory(sample/image_cv_gpumat)

?

4 .switch:

option(ENABLE_REALSENSE "Build with xxx" OFF)

if (ENABLE_REALSENSE)
?? ?add_definitions(-DENABLE_REALSENSE)
?? ?add_subdirectory(common)
endif()
