CMake Generate step failed while compling from source code

Hi all,
my computer has a GeForceGT710 graphics card (OS Linux Mint). My understanding is that I need to install pytorch from source code to avoid the “CUDA error: no kernel image is available for execution on this device” warning.
I have so far followed the instructions specified on github (GitHub - pytorch/pytorch: Tensors and Dynamic neural networks in Python with strong GPU acceleration). However, I am getting an error while compiling:

CMake Warning at modules/observers/CMakeLists.txt:12 (add_library):
Cannot generate a safe runtime search path for target caffe2_observers
because files in some directories may conflict with libraries in implicit
directories:

runtime library [libcudart.so.10.1] in /usr/lib/x86_64-linux-gnu may be hidden by files in:
  /home/mareike/miniconda3/envs/ginjinn/lib

runtime library [libcublas.so.10] in /usr/lib/x86_64-linux-gnu may be hidden by files in:
  /home/mareike/miniconda3/envs/ginjinn/lib

Some of these libraries may not be found correctly.

CMake Error at modules/observers/CMakeLists.txt:12 (add_library):
The install of the caffe2_observers target requires changing an RPATH from
the build tree, but this is not supported with the Ninja generator unless
on an ELF-based platform. The CMAKE_BUILD_WITH_INSTALL_RPATH variable may
be set to avoid this relinking step.

CMake Generate step failed. Build files cannot be regenerated correctly.

My best idea so far is to set CMAKE_BUILD_WITH_INSTALL_RPATH to TRUE. However, I am not too knowledgeable about programming, let alone cmake.
Other information that may be of use: I run gcc 9.3.0, g++ 9.3.0, cudatoolkit 10.1.243, and cudnn 7.6.5. I have everything including dependencies (numpy,… again as specified on github) installed in a conda environment. However, the error also occurs when I install everything globally.
Can someone help me to resolve this?
Best,
Mareike
