Hello,
we are facing an issue while using cmake and we have no idea how to solve or
debug it.
We have a complex and huge project (about 50 subdirectories and dependencies
everywhere), and we are facing issue regarding the link order.
There is a lot of dependencies between those projects, and to summarize, we
have two libraries A and B
A is an imported library from headers and shared lib .so declared like this
```
add_library(A SHARED IMPORTED GLOBAL)
set_target_properties(A PROPERTIES
IMPORTED_LINK_INTERFACE_LANGUAGES "C"
IMPORTED_LOCATION ${A_LIBRARY})
```
B is a system library part of a package.
We need to link A before B in every case.
In every project, we include A before B using
```
find_package(B)
target_link_libraries(${library_produced} PUBLIC A)
target_link_libraries(${library_produced} PUBLIC B)
```
but from time to time, we don't know why, the library produced link in the
wrong order (checked with ldd and make VERBOSE=1).
it links B before A.
Is there a way to find out what happens and why cmake change the link order for
some project and not all projects ?
Best regards,
Bill
