构建C＆＃x2B;＆＃x2B;通过CMAKE与OpenCV和DLIB库的项目
我将C ++项目与OpenCV和DLIB库一起使用。我有cmakelists.txt：
cmake_minimum_required(VERSION 3.20.0)
project(project1)
find_package(OpenCV REQUIRED)
include(FetchContent)
FetchContent_Declare(dlib
GIT_REPOSITORY https://github.com/davisking/dlib.git
GIT_TAG v19.18
)
FetchContent_MakeAvailable(dlib)
add_executable(project1 main.cpp)
target_link_libraries(project1 ${OpenCV_LIBS} dlib::dlib)
target_compile_options(project1 PUBLIC "$<$<CONFIG:RELEASE>:${MY_RELEASE_OPTIONS}>")
我在cygwin cmake中写作.. -g“ unix makefiles”。我使用“ Unix Makefiles”来创建用于命令“ make”的makefile。在此之后，我写了制作，但是结果我会出现错误：
collect2: error: ld execution ended with return code 1
make[2]: *** [CMakeFiles/project1.dir/build.make:123: project1.exe] Error 1
make[1]: *** [CMakeFiles/Makefile2:115: CMakeFiles/project1.dir/all] Error 2
make: *** [Makefile:91: all] Error 2
解决此问题需要做什么？
I use c++ project with opencv and dlib libraries. I have CMakeLists.txt:
cmake_minimum_required(VERSION 3.20.0)
project(project1)
find_package(OpenCV REQUIRED)
include(FetchContent)
FetchContent_Declare(dlib
GIT_REPOSITORY https://github.com/davisking/dlib.git
GIT_TAG v19.18
)
FetchContent_MakeAvailable(dlib)
add_executable(project1 main.cpp)
target_link_libraries(project1 ${OpenCV_LIBS} dlib::dlib)
target_compile_options(project1 PUBLIC "lt;lt;CONFIG:RELEASE>:${MY_RELEASE_OPTIONS}>")
I write in cygwin cmake .. -G "Unix Makefiles". I use "Unix Makefiles" to create makefile that use to command "make". After this I write make, but as a result I get error:
collect2: error: ld execution ended with return code 1
make[2]: *** [CMakeFiles/project1.dir/build.make:123: project1.exe] Error 1
make[1]: *** [CMakeFiles/Makefile2:115: CMakeFiles/project1.dir/all] Error 2
make: *** [Makefile:91: all] Error 2
What I need to do to fix this problem?
