Question about compiling #3

Open IvanChen777 opened 1 year ago

Hi, @pmkalshetti , when I implement your code by your instruction in readme, I have met several issues. I don't know if you could help me. First, when I run your first command(cmake -S . -B build -DCMAKE_BUILD_TYPE=Release), I get -- Found pybind11: /opt/anaconda3/envs/adaexam/include (found version "2.6.1" ) -- Could NOT find Open3D (missing: Open3D_DIR) -- Configuring done (0.5s) -- Generating done (0.0s)

I have already installed the Open3D following Cmakelist.txt row 20(find_package(Open3D HINTS ${CMAKE_INSTALL_PREFIX}/lib/CMake)), on my computer, the path is (/usr/local/lib/CMake/Open3D), therefore, I think it should work, could you please tell me why there is an Could Not find Open3D(missing:Open3D_DIR) in the output.

Second, when I run your second command(cmake --build build/ ), I met issues again, as shown below: clang: error: unsupported argument 'libomp' to option '-fopenmp=' ninja: build stopped: subcommand failed.

Do you have any idea why it happens?

Thank you in advance!
