Error during linking of examples

Hello, I am trying to compile cupoch version 0.1.9.1 on Ubuntu 18. Since Ubuntu comes with CMake 3.10.2, I downloaded the cmake 3.20.2 binary. Below are my build steps. The build works most of the way, but it crashes when it tries to link the executables in examples.

git clone https://github.com/neka-nat/cupoch.git --branch v0.1.9.1 --recurse
cd cupoch
mkdir -p build; cd build;
~/Downloads/cmake-3.20.2-linux-x86_64/bin/cmake ..
make -j4
...

Googling these errors suggests that the libraries are not being linked in the correct order, but so far I was unable to fix this. I also tried several previous cupoch releases but I got the exact same error.

Hi,
Thank you for the reporting!
How about using the package's glfw instead of the environment's glfw?

cmake .. -DBUILD_GLEW=ON -DBUILD_GLFW=ON

Yes, thank you! With this I was able to compile everything.
