Thanks, it works.
Since the library is found in Find* script, I have to check if it is static.
So I ended up with this:
if("${MMDB_LIBRARY}" MATCHES "\\.a$")
# it cannot be just "UNKNOWN IMPORTED", because
# IMPORTED_LINK_INTERFACE_LANGUAGES is respected only for "STATIC IMPORTED"
add_library(mmdb_cxxlib STATIC IMPORTED)
else()
add_library(mmdb_cxxlib UNKNOWN IMPORTED)
endif()
set_target_properties(mmdb_cxxlib PROPERTIES
IMPORTED_LOCATION ${MMDB_LIBRARY}
IMPORTED_LINK_INTERFACE_LANGUAGES "CXX")
...
foreach(p ...)
set_property(TARGET ${p} PROPERTY LINKER_LANGUAGE Fortran)
endforeach(p)
Two feature requests come to my mind:
- IMHO it would be better if the language of external library didn't
change linker language,
- and a function that tells if the library is static would also be nice
Cheers
Marcin
