   4 # This CMake project will by default create a library called openjpeg

   6 # you will eventually like to prefix the library to avoid linking confusion
   7 # For this purpose you can define a CMake var: OPENJPEG_NAMESPACE to whatever you like
   8 # e.g.:
   9 # SET(OPENJPEG_NAMESPACE "GDCMOPENJPEG")
