1. locate Error

/home/sincos/RGBDemo-0.7.0-Source/build/nestk/deps/openni/Nite/Samples/Players

find the file path, and change the CMakeList.txt file:

# And make it link against these libs.
# ---------------------------------------
find_library(OpenGL GLUT_LIB glut)
if(DEFINED OPENNI_PLATFORM_APPLE)
 find_library(OPENGL_LIB OpenGL)
endif(DEFINED OPENNI_PLATFORM_APPLE)


target_link_libraries(
 ${VIEWER_EXE}
 ${OPENNI_LIB_NAME}
 ${GLUT_LIB}
 ${OPENGL_LIB}
 ${OPENGL_LIBRARIES}  #libGL new add line
)

if you find the same error, you can solve it by the method!

Cause: The link library file could not be found

Thanks for reply. After 3 years somebody replied.

It took me a week to compile it! The result runs with a segment error! I am helpless.
