Каков идиоматический способ нарезать массив относительно обоих его концов?

Я использую эти два файла cmake для создания моих проектов OpenGL, и все они работают хорошо.

Я тестирую только эти два файла cmake в Deepin Linux. Deepin Linux - это китайская система Linux, такая как Ubuntu или Debian.

Во-первых, основной CMakeLists.txt

cmake_minimum_required(VERSION 3.1.0)
project(project_name)

set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_CURRENT_SOURCE_DIR}/CMakeModules/")

find_package(OpenGL REQUIRED)
find_package(FREEGLUT REQUIRED)
find_package(GLEW REQUIRED)

if(NOT ${OPENGL_FOUND})
    message("OPENGL not found")
endif()

include_directories(
    ${PROJECT_SOURCE_DIR}
    ${FREEGLUT_INCLUDE_DIR}
    ${GLEW_INCLUDE_DIR}
    ${OPENGL_INCLUDE_DIR}
    )

message(${OPENGL_INCLUDE_DIR})
add_executable(${PROJECT_NAME}  ${PROJECT_SOURCE_DIR}/filename.cpp) 
target_link_libraries(${PROJECT_NAME} 
${OPENGL_LIBRARY}
${FREEGLUT_LIBRARY}
${GLEW_LIBRARY}
)

Во-вторых, файл cmake find GLUT в каталоге CMakeModules

# Try to find the FREEGLUT library
#
# FREEGLUT_INCLUDE_DIR
# FREEGLUT_LIBRARY
# FREEGLUT_FOUND

FIND_PATH(
  FREEGLUT_INCLUDE_DIR GL/freeglut.h GL/gl.h GL/glu.h GL/glew.h
  ${CMAKE_INCLUDE_PATH}
  $ENV{include}
  ${OPENGL_INCLUDE_DIR}
  /usr/include
  /usr/local/include
)

SET(STORE_CMAKE_FIND_FRAMEWORK ${CMAKE_FIND_FRAMEWORK})
SET(CMAKE_FIND_FRAMEWORK NEVER)

FIND_LIBRARY(
  FREEGLUT_LIBRARY
  NAMES freeglut_static freeglut glut GL
  PATH
    /opt/local/lib
    ${CMAKE_LIBRARY_PATH}
    $ENV{lib}
    /usr/lib
    /usr/local/lib
)

SET(CMAKE_FIND_FRAMEWORK ${STORE_CMAKE_FIND_FRAMEWORK})

IF (FREEGLUT_INCLUDE_DIR AND FREEGLUT_LIBRARY)
   SET(FREEGLUT_FOUND TRUE)
ENDIF (FREEGLUT_INCLUDE_DIR AND FREEGLUT_LIBRARY)

IF (FREEGLUT_FOUND)
   IF (NOT FREEGLUT_FIND_QUIETLY)
      MESSAGE(STATUS "Found FREEGLUT: ${FREEGLUT_LIBRARY}")
   ENDIF (NOT FREEGLUT_FIND_QUIETLY)
ELSE (FREEGLUT_FOUND)
   IF (FREEGLUT_FIND_REQUIRED)
      MESSAGE(FATAL_ERROR "Could not find FREEGLUT")
   ENDIF (FREEGLUT_FIND_REQUIRED)
ENDIF (FREEGLUT_FOUND)
