Hi CMake Experts,
I'm trying to add support for VxWorks to CMake.
My current dilemma is that the Compiler ID link test is failing because my library link path isn't being used, and libraries aren't being found.
I've set the library path in all the obvious places ( or so I thought,) what setting am I missing?
Why isn't CMAKE_C_LINK_FLAGS being used?
My end goal is to compile Eigen and OpenCV
Best of the season, and thanks,
