Fix conan GENERATORS for conan 2.x

[davidradkowski]

conan 2.x requires a change to GENERATORS in CMakeLists.txt from:
GENERATORS cmake_find_package to GENERATORS CMakeDeps

Ah, thanks for reporting!
Installing conan as follows should fix the issue for now:

pip install --user conan==1.59.0

I updated all README.md files accordingly. I will keep this issue open until I come around updating conan for it.
