# Creates an imported wrapper target that links against either a Qt bundled package

# or a system package.

# Used for consuming 3rd party libraries in Qt.

# Example: Creates WrapFreetype::WrapFreetype linking against either

||
|
|
# Qt6::BundledFreetype or WrapSystemFreetype::WrapSystemFreetype.

# find_package()s WrapPNG, the nested call would override the parent call variables, due to macros
|

# using the same scope.
