Hi,

usually, libraries are linked using their full path, so we shouldn't need a *_LIBRARY_DIRS variable for linking (there are exceptions for GDCM due to its build system).

The full path is known to external projects via the "exports file" of MITK. I think that qtsingleapplication is missing from the export set which results in it being linked using the library name directly.

@Matt Could you try and add "qtsingleapplication" to the "targets_to_export" CMake variable in MITK/CMakeLists.txt:920 ?

@Miklos Yes, the MITK Workbench builds because "qtsingleapplication" is a known target to the MITK build system. Your code looks good but you should remove the "include_directories" statement in your "After" version (mitk_use_modules takes care of that).

Thanks,
Sascha

Weird, because the MitkWorkbench builds well with the new mitk_use_modules function.

I switched back to the deprecated MITK_USE_MODULE macro, now I get some ugly CMake warnings, but the application builds and runs.

The change I made (and what I had to revert):

Before:

MITK_USE_MODULE(niftkCore)
MITK_USE_MODULE(qtsingleapplication)
include_directories(${ALL_INCLUDE_DIRECTORIES})

After:

mitk_use_modules(TARGET ${MY_APP_NAME} MODULES qtsingleapplication niftkCore)
include_directories(${ALL_INCLUDE_DIRECTORIES})

And I put the new calls after the FunctionCreateBlueBerryApplication call.

Sascha, do you see any problem with this code?

Cheers,
Miklos

    Hi All,

    I am looking at mitkFunctionUseModules.cmake and I can’t see how a
    specified module’s library directories are added to
    ALL_LIBRARY_DIRS or similar.
    Our app can’t link to qtsingleapplication because, the variable
    qtsingleapplication_LIBRARY_DIRS is never added to a list of
    directories.

    Is that right?

    Thanks

    Matt
