+If you experience any conan.cmake errors like `Conan install failed='1'`, cd
+into the directory of the project which causes the errors and try to install
+the packages directly with the conan cli:
+```bash
+mkdir conan_build && cd conan_build
+conan install ..
+```
+This will give you a more verbose error message like
+`ERROR: Unable to find 'scigl_render/0.6@tuebel/testing' in remotes` which means
+you probably forgot to add a repository from above.
