# Main CMakeLists.txt to build the OpenJPEG project using CMake (www.cmake.org)
# Written by Mathieu Malaterre

# This CMake project will by default create a library called openjpeg
# But if you want to use this project within your own (CMake) project
# you will eventually like to prefix the library to avoid linking confusion
# For this purpose you can define a CMake var: OPJ_PREFIX to whatever you like
# e.g.:
# SET(OPJ_PREFIX "gdcm")
# Also if you want to test (CTest driven) you need to define :
# OPJ_STANDALONE to 1, e.g
# OPJ_STANDALONE:BOOL=1
