Description
i'm having troubles with setting up a scalable setup:
i define a library in subdir/CMakeLists.txt:
add_library(lib lib.cpp) find_package(Qt6 COMPONENTS Core Gui Widgets Qml Quick REQUIRED) target_link_libraries(lib Qt6::Gui Qt6::QCocoaIntegrationPlugin)
this library links to qt6 libraries.
my executable in the root `CMakeLists.txt` consumes the library:
project(foo) cmake_minimum_required(VERSION 3.20 FATAL_ERROR) add_subdirectory(subdir) add_executable(exe main.cpp) target_link_libraries(exe lib)
this gives me the following cmake configuration error:
CMake Error at CMakeLists.txt:8 (target_link_libraries):
Error evaluating generator expression:
$<TARGET_OBJECTS:Qt6::Gui_resources_1>
Objects of target "Qt6::Gui_resources_1" referenced but no such target
exists.

afaict the qt/cmake targets are IMPORTED targets, which are not GLOBAL. therefore the generator expression expands in a context where this target does not exist anymore. things work again once i move the `find_package` expression to the root CMakeLists.txt. unfortunately this is not a solution that i can easily apply to my whole codebase, which is rather modular and as many different consuming endpoints
