CMake RelWithDebInfo links to Debug libs

Question

I have a project which links to half a dozen libraries, among them OpenCV.
Since Release variant is crashing, while Debug is working fine (just a lot slower), I wanted to co

Answer 1

you could disable level 2 optimizations with the default cmake release build using the below snippet. This would still pick release opencvworld (build with full optimizations) from the un-optimized (yet Release) app code. Using this we can step through the app's code line-by-line with full variable visibility.. as good as the debug build minus the need to link with debug opencv or mixing the CRTs or doing a full debug build of all components involved.

if (WIN32)

  SET (CMAKE_CXX_FLAGS_RELEASE "/Zi /Od")

  SET_TARGET_PROPERTIES(
   xyz PROPERTIES 
   LINK_FLAGS 
   "/DEBUG /OPT:REF /OPT:ICF"
  )

endif (WIN32)
