midas-cpp's Issues

Problem when link ld_libraries to inference_midas

Hi, I meet a problem during link

/usr/bin/ld: CMakeFiles/midas_inference.dir/src/inference_midas.cpp.o: in function main':
inference_midas.cpp:(.text.startup+0x6c): undefined reference to cv::imread(std::string const&, int)' /usr/bin/ld: inference_midas.cpp:(.text.startup+0x350): undefined reference to cv::namedWindow(std::string const&, int)'
/usr/bin/ld: inference_midas.cpp:(.text.startup+0x3a2): undefined reference to cv::imshow(std::string const&, cv::_InputArray const&)' collect2: error: ld returned 1 exit status make[2]: *** [CMakeFiles/midas_inference.dir/build.make:155: midas_inference] Error 1 make[1]: *** [CMakeFiles/Makefile2:78: CMakeFiles/midas_inference.dir/all] Error 2 make: *** [Makefile:84: all] Error 2

enviroment:
Ubuntu 20.04
opencv 4.5.2

What I have tried:
1.re-compile the opencv lib from source, and add the path to CMAKE_PREFIX_PATH, and output the include_dir of opencv, it seems alright, but I still meet the problem above, the output of cmake is

2. I have tried to add a linker flag in cmakelist.txt, it is useless and I comments out it then.

SET(GGC_OPENCV_LINK_FLAG "-lopencv_highgui") SET(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} ${GGC_OPENCV_LINK_FLAG}")

make error: undefined reference to opencv

Hi, I'm trying to compile your code using c++17 and opencv4.2. But I've been encountering an linking error:

Do you have any idea how to fix this?

MiDaS 2.1

Just to confirm, this is compatible with MiDaS <= 2.1

Hi,
I meet 2 problems

1. during cmake, I received 2 warnings in ADD_EXECUTABLE

`CMake Warning at CMakeLists.txt:33 (ADD_EXECUTABLE):
Cannot generate a safe runtime search path for target midas_inference
because there is a cycle in the constraint graph:

dir 0 is [/home/kunbpc/Codes/depth/MiDaS-cpp/build]
dir 1 is [/home/kunbpc/Installed/Anaconda3/envs/pytorch/lib]
  dir 3 must precede it due to runtime library [libcufft.so.10]

dir 3 is [/usr/local/cuda/lib64]

dir 4 is [/usr/local/cuda/lib64/stubs]

Some of these libraries may not be found correctly.

2. In make, there are many errors, and the last one is
