LINK error 1104: cannot find .lib file for new device

[zoez7]

Hello,

I am trying to add a new ultrasound probe device called Clarius to PlusDataCollection. I got the LINK error below but was not sure how to resolve it. I'm wondering if you could provide some guidance on this?

Here's the script I added in the PlusDataCollction/CMakeList.txt:
`IF(PLUS_USE_CLARIUS)
FIND_PACKAGE(Threads REQUIRED)
FIND_PACKAGE(CLARIUS REQUIRED)

SET(CLARIUS_SRCS
Clarius/vtkPlusClarius.cxx
)

IF(MSVC OR ${CMAKE_GENERATOR} MATCHES "Xcode")
SET(CLARIUS_HDRS
Clarius/vtkPlusClarius.h
)
ENDIF()

LIST(APPEND ${PROJECT_NAME}_HDRS
${CLARIUS_HDRS}
)

LIST(APPEND ${PROJECT_NAME}_SRCS
${CLARIUS_SRCS}
)

LIST(APPEND ${PROJECT_NAME}_INCLUDE_DIRS
${CMAKE_CURRENT_SOURCE_DIR}/Clarius
)

SET(External_Libraries_Install ${External_Libraries_Install} ${CLARIUS_LIB_DIR}/listen${CMAKE_STATIC_LIBRARY_SUFFIX})
LIST(APPEND ${PROJECT_NAME}_LIBS
Clarius
)
ENDIF()`

Is Clarius a CMake target? Defined either in a find module (FindClarius.cmake) or a CMakeified project (Clarius_DIR which contains ClariusConfig.cmake)?

Hello Adam,

Thanks for the reply.

Clarius is not a Cmake target. I have added a find module(FindClarius.cmake) in PlusBuild/Modules. When I run Config in the CMake GUI, it indicates that Clarius is found:

However, I think this linking error was produced because it was unable to open the static library file built from PlusDataCollection/vtkPlusClarius.cxx?

Thanks,
Zoe

Hello Adam,

I think my wording earlier was not clear. I am just confused by the highlighted part here:

I am assuming I only need to pass in the path to .lib files provided by Clarius SDK for <Your_Device_Library_Name>?

[adamrankin]

Ah, does your find module package things up into a CMake target via

...
ADD_LIBRARY(<targetName> <STATIC|SHARED> IMPORTED)
...

?

An example of one I made is here:

Hi Adam,

Thanks for providing the examples.

I'm getting this interesting error now.

I'm not sure why it is trying to find lib.obj. The Clarius sdk provides .dll, .lib and .h files.

Here's how my FindClarius.cmake file looks like:

Also, here is the cmake script in PlusLib/srcs/PlusDatacollection/CMakeLists.txt

Thanks,
Zoe

Very close! The find module IMPORTED_LOCATION is the full file path to the .dll

https://cmake.org/cmake/help/latest/prop_tgt/IMPORTED_LOCATION.html

I led you a bit astray by linking a linux example, on Windows you'll need to also define

https://cmake.org/cmake/help/latest/prop_tgt/IMPORTED_IMPLIB.html

which is the full file path to the .lib file

Here is a Windows example:
