How to Build moderngpu

I have

• Mint/Ubuntu 18.04 running GCC 7.4, CUDA 10.0 and Driver 410.73
• cmake-3.22.3 binary.
• GeForce 840M with Compute Capability (CC) 5.0

I could build it but not run it. Because CUDA_ARCHITECTURES is set higher. Let’s change it to 50

git clone https://github.com/moderngpu/moderngpu.git
cd moderngpu
mkdir build && cd build
~/install/cmake-3.22.3-linux-x86_64/bin/cmake ..
make
./bin/test_segreduce

On P100.

• Not working with cmake 3.23
• Just use 3.19
• scl enable devtoolset-6 bash
• and it should work.
