Summary: Imported libraries go out of scope after call to
target_link_libraries().
Description:
I have a project where module lib - a library - depends on Qt, so it calls
find_package(Qt5 ...) and target_link_libraries(lib Qt5::Core). Later I call
target_link_libraries(app lib).
The cmake configure step runs through without problems, but the generate step
halts with the message:
Target "app" links to target "Qt5::Core" but the target was not found.
Perhaps a find_package() call is missing for an IMPORTED target, or an
ALIAS target is missing?
According to the documentation the target Qt5::Core is out of scope for 'app'
since app is not in a subdirectory of the directory where add_library(...
IMPORTED) was made, but I would argue that this is a bug since the target was in
scope when the call add_library(lib Qt5::Core) was made.
This issue is not specific to Qt and I'm aware that it could be fixed on their
side by calling add_library(... IMPORTED GLOBAL). I'm hoping it could be fixed
on the cmake side, though.
Steps to Reproduce:
git clone https://github.com/bjornpiltz/cmake_bug.git cmake_bug
mkdir work
cd work
cmake -DCMAKE_PREFIX_PATH=<Qt5>/lib/cmake/ ../cmake_bug/
Additional Information:
This issue is platform independent.
