Error during installation

[matygr]

Hi,
After following the instructions in the "Building the C++ package with CMake" section I'm getting the following error:

CMake Error at doc/CMakeLists.txt:19 (add_custom_target):
  add_custom_target cannot create target "doc" because another target with
  the same name already exists.  The existing target is a custom target
  created in source directory
  "<path to dir location>/gtsam-quadrics-master/gtsam/doc".
  See documentation for policy CMP0002 for more details.

After removing the following lines from the CMakeLists.txt:

find_package(Doxygen)

if (DOXYGEN_FOUND)
  add_subdirectory(doc)
endif()

The build passed successfully.

Am I'm missing something?

thanks

Thanks for reporting @matygr .

Can I confirm what line of the installation instructions you're receiving the error. Is it the cmake --build . -j$(nproc) step or are you running another make <TARGET> step afterwards?

Hi,
The error is encountered while running the following command:
cmake -DBUILD_PYTHON_WRAP=ON ..

Thanks for the quick response.

I encoutered the same Error while during installation.
