DLT Logging with QT: "DLT" package not found

Super_QT_Enthusiast

Hello,

in my project I currently try to integrate DLT logging with a specific dlt-contextId for my application.
So therefore I used

Q_DECLARE_LOGGING_CATEGORY(MyLogCategory) and
QDLT_LOGGING_CATEGORY(MyLogCategory, "MyLogCat.logs",  "MYLO", "My Logs")

to define my log category. And

qWarning(MyLogCategory) << "some log blabla";

for the logging itself. All fine so far!

To support the logging I added DltLogging to my cmake CMakeLists.txt:

find_package(Qt6DltLogging REQUIRED)

... other stuff ...

target_link_libraries(
  my_project
  PRIVATE
....other libs
Qt6::Quick
Qt6::DltLogging
)

Now when running cmake the issues start occuring:
cmake trys to find package Qt6DltLogging which successfull. Internal Qt6DltLogging uses Qt6DltLoggingDependencies.cmake to find a package called "DLT" which is not found on my computer. This results in failing of cmake. Full error:

CMake Warning at .../share/cmake-3.16/Modules/CMakeFindDependencyMacro.cmake:47 (find_package):
  By not providing "FindDLT.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "DLT", but
  CMake did not find one.

  Could not find a package configuration file provided by "DLT" with any of
  the following names:

    DLTConfig.cmake
    dlt-config.cmake

  Add the installation prefix of "DLT" to CMAKE_PREFIX_PATH or set "DLT_DIR"
  to a directory containing one of the above files.  If "DLT" provides a
  separate development package or SDK, be sure it has been installed.

  .../lib/cmake/Qt6DltLogging/Qt6DltLoggingConfig.cmake:40 (include)
  CMakeLists.txt:3 (find_package)


CMake Error at CMakeLists.txt:3 (find_package):
  Found package configuration file:

    .../lib/cmake/Qt6DltLogging/Qt6DltLoggingConfig.cmake

  but it set Qt6DltLogging_FOUND to FALSE so package "Qt6DltLogging" is
  considered to be NOT FOUND.  Reason given by package:

  Qt6DltLogging could not be found because dependency DLT could not be found.

  Configuring with -DQT_DEBUG_FIND_PACKAGE=ON will print the values of some
  of the path variables that find_package uses to try and find the package.



-- Configuring incomplete, errors occurred!

When I search my whole system for DLTConfig.cmake or dlt-config.cmake it is not on the disc.
Any ideas what ideas how to resolve this issue?

Thanks in advance & regards

@Super_QT_Enthusiast Looking in the source, I would expect you should have a FindDLT.cmake file in cmake's search path so that:

find_package(DLT REQUIRED)

might get closer to the result.
