Thanks so much for taking time and helping out. I see. I’ll open also an issue for this and suggest clarifying this in the find modules documentation. Because, this I believe is crucial part from the user perspective (user who doesn’t develop application or its CMake-based build system and needs to know how to build some app). Having 3 ways to select some path for some library is confusing (specially these <PackageNam>_ROOT and <PACKAGENAME>_ROOT variables).
