We are developping plugins for applications that just recently switch to the new C++ ABI on linux (Dual ABI)
So here is my problem. I need to compile my plugins with
–for the new ABI
target_compile_definitions(${target_name} PUBLIC _GLIBCXX_USE_CXX11_ABI=1)
–for the old ABI
target_compile_definitions(${target_name} PUBLIC _GLIBCXX_USE_CXX11_ABI=0)
Thta works great until we start using external libraries. If in understood well the external libraries also need to be compiled with the same value of _GLIBCXX_USE_CXX11_ABI.
Now we use find_package for all library dependencies. However i dont see any parameters that would allow me to ask find_package to find with _GLIBCXX_USE_CXX11_ABI enabled or disables.
I can always create my own findXXX.cmake files to make it happen but i was wondering if there was a standard way of getting the right library.
Thank you in advance for you help.
