Outdated conanfile since conan 2.0 release

[makru86]

To be able to run conan install .. --build missing -s build_type=Debug I had to fix conanfile.txt:

diff --git a/conanfile.txt b/conanfile.txt
index b2423bb..f7a03b7 100644

I believe those changes required because of conan 2.0 update. https://docs.conan.io/2/
