I am using cmake to create make files for a rather complex project today. Is there a standard way of using cmake to find the CVB includes etc that is needed. Today my cmake pipeline does not find the FindCVB.cmake file in /opt/cvb/cmake. I could start to manually set things in the CMakeLists.txt file but i first I wonder if there is a standard way?

Hi,

the standard way to find CVB using cmake is shown in the tutorials (e.g. GrabConsole)  
It uses the environment variable “CVB” which must exist on a valid installation.  
Once the “FindCVB.cmake” script is in the module path you can simply ask CMake to find CVB.

```auto
# Make CMake aware of our FindCVB.cmake module
set(CMAKE_MODULE_PATH "${CMAKE_MODULE_PATH}" "$ENV{CVB}/cmake")
find_package(CVB REQUIRED)

```

Please note it also takes care of the required include directories. For linking you can then pick the libraries needed. All dependencies to additional CVB libraries (in this case CVB::CVCImg) will automatically resolved.

```auto
target_link_libraries(GrabConsoleExample 
  CVB::CVCDriver 
  CVB::CVCUtilities 
  CVB::CVGenApi
)

```

By the way, this is not C++ specific and is also valid for the classic C API.

Hi Andreas,

Thanks for the answer! Works fine now.

Another question: I am using PTP sync on the cameras and would like to trigger each camera on a clock modululs event. Is there some instruction on how to achieve this?
