Building mylibrary as a static library is OK. Do prefab not support shared library?

find_package(mylibrary REQUIRED CONFIG) ,the first parameter "mylibrary " should be the same with the name of your prefab-publishing project 's name !
find_package(mylibrary REQUIRED CONFIG) ,the first parameter "mylibrary " should be the same with the name of your prefab-publishing project 's name !
Yes, but the name of the sample library prefab/prefab_publishing/mylibrary is also "mylibrary". The name is not the problem.
