[CMake] how to set ar/ranlib flags per target

[Verweij, Arjen]

Kelly,

I suffer from the same problem and solved it like this:

SET(CMAKE_C_ARCHIVE_CREATE "<CMAKE_AR> -X64 cr <TARGET> <LINK_FLAGS> <OBJECTS>")
SET(CMAKE_C_ARCHIVE_APPEND "<CMAKE_AR> -X64 r  <TARGET> <LINK_FLAGS> <OBJECTS>")
SET(CMAKE_C_ARCHIVE_FINISH "<CMAKE_RANLIB> -X64 <TARGET>")
SET(CMAKE_CXX_ARCHIVE_CREATE ${CMAKE_C_ARCHIVE_CREATE})
SET(CMAKE_CXX_ARCHIVE_APPEND ${CMAKE_C_ARCHIVE_APPEND})
SET(CMAKE_CXX_ARCHIVE_FINISH ${CMAKE_C_ARCHIVE_FINISH})
SET(CMAKE_Fortran_ARCHIVE_CREATE ${CMAKE_C_ARCHIVE_CREATE})
SET(CMAKE_Fortran_ARCHIVE_APPEND ${CMAKE_C_ARCHIVE_APPEND})
SET(CMAKE_Fortran_ARCHIVE_FINISH ${CMAKE_C_ARCHIVE_FINISH})

Does that help you?

Regards,
Arjen
