Find pre-installed Open3D package in CMake

Find Pre-Installed Open3D Package in CMake

This is one of the two CMake examples showing how to use Open3D in your CMake project:

• Find Pre-Installed Open3D Package in CMake
• Use Open3D as a CMake External Project

For more details, check out the Open3D repo and Open3D docs.

Step 1: Compile and install Open3D

Follow the Open3D compilation guide, compile and install Open3D in your preferred location. You can specify the installation path with CMAKE_INSTALL_PREFIX and the number of parallel jobs to speed up compilation.

On Ubuntu/macOS:

git clone --recursive https://github.com/intel-isl/Open3D.git
cd Open3D
mkdir build
cd build
cmake -DBUILD_SHARED_LIBS=ON -DCMAKE_INSTALL_PREFIX=${HOME}/open3d_install ..
make install -j 12
cd ../..

On Windows:

git clone --recursive https://github.com/intel-isl/Open3D.git
cd Open3D
mkdir build
cd build
cmake -DBUILD_SHARED_LIBS=ON -DCMAKE_INSTALL_PREFIX=C:\open3d_install ..
cmake --build . --config Release --parallel 12 --target install
cd ..\..

Note: -DBUILD_SHARED_LIBS=ON is recommended if -DBUILD_CUDA_MODULE=ON.

Step 2: Use Open3D in this example project

On Ubuntu/macOS:

git clone https://github.com/intel-isl/open3d-cmake-find-package.git
cd open3d-cmake-find-package
mkdir build
cd build
cmake -DOpen3D_ROOT=${HOME}/open3d_install ..
make -j 12
./Draw

On Windows:

git clone https://github.com/intel-isl/open3d-cmake-find-package.git
cd open3d-cmake-find-package
mkdir build
cmake -DOpen3D_ROOT=C:\open3d_install ..
cmake --build . --config Release --parallel 12
Release\Draw

Hi，I'm building open3d from source on mac.But when i compile according your script, it fails and throws the following error:

what can i do now to complete the build?

jsoncpp conflicts？

Hi, I use this repo as a start project,
when I wrote in .cpp

#include <json/json.h>

I got

fatal error: json/json.h: No such file or directory

if I install jsoncpp via vcpkg, and add

target_link_libraries(Draw PRIVATE
    jsoncpp_object
    jsoncpp_static
    Open3D::Open3D
    )

then I got many multiple definition link errors like:

multiple definition of `Json::StreamWriterBuilder::validate(Json::Value*) const'; /home/hong/devs/vcpkg/installed/x64-linux/debug/lib/objects-Debug/jsoncpp_object/json_writer.cpp.o:/home/hong/devs/vcpkg/buildtrees/jsoncpp/src/3918c327b1-034a82149a.clean/src/lib_json/json_writer.cpp:1204: first defined here
collect2: error: ld returned 1 exit status

I looked Open3D code, seems jsoncpp lib is not installed as 3rdparty lib when make install?
any suggestions or work around?
Thanks

I want build my project with open3d and opencv ,but some errors occur.Linking the both two library rusult in opencv function not be found.

Build fails due to CUDA error

Hi!

I face a problem with building this project if the source code includes CUDA related operation.
The code example is the following:

`int main(int argc, char* argv[]) {
using namespace open3d;

if (argc < 4 ||
    utility::ProgramOptionExistsAny(argc, argv, {"-h", "--help"})) {
    PrintHelp();
    return 1;
}

// Color and depth
std::string color_folder = std::string(argv[1]);
std::string depth_folder = std::string(argv[2]);

std::vector<std::string> color_filenames;
utility::filesystem::ListFilesInDirectory(color_folder, color_filenames);
std::sort(color_filenames.begin(), color_filenames.end());

std::vector<std::string> depth_filenames;
utility::filesystem::ListFilesInDirectory(depth_folder, depth_filenames);
std::sort(depth_filenames.begin(), depth_filenames.end());

if (color_filenames.size() != depth_filenames.size()) {
    utility::LogError(
            "The numbers of color and depth files mismatch. "
            "Please provide folders with same number of images.");
}

// Trajectory
std::string trajectory_path = std::string(argv[3]);
auto trajectory =
        io::CreatePinholeCameraTrajectoryFromFile(trajectory_path);

// Intrinsics
std::string intrinsic_path = utility::GetProgramOptionAsString(
        argc, argv, "--intrinsic_path", "");
camera::PinholeCameraIntrinsic intrinsic = camera::PinholeCameraIntrinsic(
        camera::PinholeCameraIntrinsicParameters::PrimeSenseDefault);
if (intrinsic_path.empty()) {
    utility::LogWarning("Using default Primesense intrinsics");
} else if (!io::ReadIJsonConvertible(intrinsic_path, intrinsic)) {
    utility::LogError("Unable to convert json to intrinsics.");
}

auto focal_length = intrinsic.GetFocalLength();
auto principal_point = intrinsic.GetPrincipalPoint();
Tensor intrinsic_t = Tensor::Init<double>(
        {{focal_length.first, 0, principal_point.first},
         {0, focal_length.second, principal_point.second},
         {0, 0, 1}});`

The following log is part of the error output:

/usr/bin/ld: /usr/local/cuda-11.6/lib64/libcublasLt_static.a(cublasMempoolNoEvents.cpp.o): in function cublasDynamicSizePoolNoEvents::tearDown()': cublasMempoolNoEvents.cpp:(.text+0x92a): undefined reference to cudaDeviceSynchronize'
/usr/bin/ld: cublasMempoolNoEvents.cpp:(.text+0x964): undefined reference to cudaFree' /usr/bin/ld: cublasMempoolNoEvents.cpp:(.text+0x9d7): undefined reference to cudaFree'
collect2: error: ld returned 1 exit status
make[2]: *** [CMakeFiles/Draw.dir/build.make:185: Draw] Error 1
make[1]: *** [CMakeFiles/Makefile2:83: CMakeFiles/Draw.dir/all] Error 2
make: *** [Makefile:91: all] Error 2

If I comment out the tensor part it compiles.
Do I need to link somehow CUDA libraries in the CMakeLists.txt file?

Thanks

Build Failed: Cannot find libc++ and libc++abi

Thanks for sharing this tutorial.
I have downloaded pre-installed Open3D git and use the given cmake command ``cmake -DBUILD_SHARED_LIBS=ON -DCMAKE_INSTALL_PREFIX=${HOME}/open3d_install .. to install, but I got this:

-- Searching in for libc++ and libc++abi

CMake Error at 3rdparty/find_dependencies.cmake:1317 (message):
  Cannot find matching libc++ and libc++abi libraries with version >=7.
Call Stack (most recent call first):

However, I checked this path with ls /usr/lib/llvm-13/lib | grep -i libc++ and got libc++ and libc++abi at this path.
Output:

libc++.a

libc++abi.so.1.0
libc++experimental.a
libc++.so
libc++.so.1
libc++.so.1.0

I appreciate for your reply.

not working and bad result when I run ICP

ExternalProject_Add

Hi,

Do you have an example how to use open3D in CMake with command ExternalProject_Add?

Since downloading and building Open3D is a very long process, I would like to ask this beforehand.
The reason to ask is that I am using other libraries and would like to download and compile them all at once using one CMakeLists.txt .

I am using ExternalProject to download CGAL, Boost, Eigen and Cilantro and link to an executable.
