I am now having a problem with transitive dependencies. I need all
libraries that are linked in. I am missing the ones that are linked in
transitively. Modified code is, ignoring J. Decker's suggestion about
using generator expressions to get the path to the target's output.
get_property(libs TARGET a_target PROPERTY LINK_LIBRARIES)
foreach(lib ${libs})
if(TARGET ${lib})
# If this is a library, get its transitive dependencies
get_property(trans TARGET ${lib} PROPERTY INTERFACE_LINK_LIBRARIES)
foreach(tran ${trans})
if(TARGET ${tran})
get_property(path TARGET ${tran} PROPERTY LOCATION)
file(APPEND "${CMAKE_BINARY_DIR/libs.txt" "${path}\n")
endif()
endforeach()
get_property(path TARGET ${lib} PROPERTY LOCATION)
file(APPEND "${CMAKE_BINARY_DIR}/libs.txt" "${path}\n")
else()
file(APPEND "${CMAKE_BINARY_DIR}/libs.txt" "${lib}\n")
endif()
endforeach()
I am using cmake 2.8.11.2, perhaps this property doesn't do what I thought
it would with this version of cmake?
Thanks,
Tom
