# juffed CMakeLists.txt
# 
# To build juffed, you will need cmake 2.8.11.
# To build the application run this commands:
# 
# mkdir build
# cd build
# cmake .. -DCMAKE_INSTALL_PREFIX=/usr (or whatever prefix you'd like)
# make
# make install
#
# mac os x notes:
# juffed.app is build by default. There are some additions to steps above. 
# "make install" is required to get plugins working
# "make bundle" an optional make target to build bundle with all dependencies inside
#
