# This CMakeList.txt currently only supports compilation of
#a program on windows or linux, but only with the dependancies
#for oclPixelGameEngine.h

# NOTE: THIS CMAKELIST WILL NOT INSTALL DEPENDANCIES, IT WILL JUST FIND THEM AND
#COMPILE / LINK THEM RESPECTIVELY, YOU NEED TO INSTALL THEM YOURSELF

# Any issues, submit an issue, or contact the author, "Ben (plane000)#8618" on Discord

# Currently linked / compiled by default is:
#Threads (pthread), OpenGL, GLX, libPNG, X11
