cmake flow of work

  • cmake --help-module FindGLEW:
  • cmake .. 
    • will go into src/CMakeLists.txt then look for different external find_package()
  • find_package(GLEW REQUIRED QUIET)
    • goes into 'Pangolin/Modules' directory and looks for 'FindGLEW.cmake' file. If doesn't find it there then goes into '/usr/share/cmake-2.8/Modules/' to find
  • If successful then following environment variables will be set inside the 'FindGLEW.cmake' file:
    • GLEW_FOUND
    • GLEW_INCLUDE_DIR or GLEW_INCLUDES
    • GLEW_LIBRARIES or GLEW_LIBS
  •  Printing env variable:
    • MESSAGE( ${GLEW_INCLUDE_DIR}), if find_path(GLEW_INCLUDE_DIR ) is unsuccessful then message will print "GLEW_INCLUDE_DIR-NO-FOUND"
  • sudo find /usr -iname '*glew*' -print (MOST USEFUL COMMAND)
  • apt-cache search glew (FINDS THE AVAILABLE glew package for installation)
  • Reference: How package finding works
  • Reference: good
  • Reference: with Visual Studio
