Question

我试图在运行时将资源文件提供给可执行文件。我正在使用以下CMakeLists.txt。

cmake_minimum_required(VERSION 2.8)

project(open-gl-test)

find_package(OpenGL REQUIRED)
find_package(GLEW REQUIRED)
find_package(glfw3 REQUIRED)

add_executable(${PROJECT_NAME} "main.c")

message(Executable is set!)

target_link_libraries(${PROJECT_NAME} ${GLEW_LIBRARIES} ${OPENGL_gl_LIBRARY} glfw)

# List of files for which we add a copy rule.
set(data_SHADOW "basic.shader")

# We don't want to copy if we're building in the sourse dir.
if (NOT CMAKE_CURRENT_SOURCE_DIR STREQUAL CMAKE_CURRENT_BINARY_DIR)
    message(WARNING "Directories are not equal")
    foreach(item IN LISTS data_SHADOW)
        message(STATUS ${item})
        add_custom_command(
            OUTPUT "${CMAKE_CURRENT_BINARY_DIR}/res/shaders/${item}"
            COMMAND ${CMAKE_COMMAND} -E copy "${CMAKE_CURRENT_SOURCE_DIR}/res/shaders/${item}"
            DEPENDS "${CMAKE_CURRENT_SOURCE_DIR}/res/shaders/${item}"
        )
    endforeach()
else()
    message(WARNING "Directories are equal")
endif()

# Files are only copied if a target depends on them.
add_custom_target(data-target ALL DEPENDS "${CMAKE_CURRENT_SOURCE_DIR}/res/shaders/${data_SHADOW}")

这就是我访问文件的方式。

struct ShaderProgramSource source = parseShader("res/shaders/basic.shader");

但是什么也不会复制到项目构建目录，甚至消息也不会显示在 * compile output 窗口中。我收到的错误消息是：

打开文件时出错：没有这样的文件或目录

可能是什么问题？

使文件在运行时在CMake和Qt Creator中可用
