【英文标题】：error for compiling qt gui with cmake along with promoted widget

【问题描述】：

我有一个基于 ROS(catkin) 的 qt GUI 项目，它是我的 cmake

cmake_minimum_required(VERSION 2.8.0)
project(jir_seg)

find_package(catkin REQUIRED COMPONENTS qt_build roscpp)
include_directories($catkin_INCLUDE_DIRS)

catkin_package()

rosbuild_prepare_qt4(QtCore QtGui)

file(GLOB QT_FORMS RELATIVE $CMAKE_CURRENT_SOURCE_DIR ui/*.ui)
file(GLOB QT_RESOURCES RELATIVE $CMAKE_CURRENT_SOURCE_DIR resources/*.qrc)
file(GLOB_RECURSE QT_MOC RELATIVE $CMAKE_CURRENT_SOURCE_DIR FOLLOW_SYMLINKS      include/jir_seg/*.hpp)

QT4_ADD_RESOURCES(QT_RESOURCES_CPP $QT_RESOURCES)
QT4_WRAP_UI(QT_FORMS_HPP $QT_FORMS)
QT4_WRAP_CPP(QT_MOC_HPP $QT_MOC)

file(GLOB_RECURSE QT_SOURCES RELATIVE $CMAKE_CURRENT_SOURCE_DIR FOLLOW_SYMLINKS src/*.cpp)

add_executable(jir_seg $QT_SOURCES $QT_RESOURCES_CPP $QT_FORMS_HPP $QT_MOC_HPP)
target_link_libraries(jir_seg $QT_LIBRARIES $catkin_LIBRARIES )
install(TARGETS jir_seg RUNTIME DESTINATION $CATKIN_PACKAGE_BIN_DESTINATION)

它是 catkin 中自动生成的 cmake，在我的项目中，我有一个来自 qgeraphicview (JIRSEGSubClassQGV.hpp) 的子类，我向它提升了一个小部件，问题是当我编译此代码时出现此错误

UIC 添加到 ui_*.h 的标题是 '#include "JIRSEGSubClassQGV.hpp"'，我尝试了一些方法来解决，但没有一个不起作用，感谢任何帮助。

【问题讨论】：

我不确定，但可能是explicit reference on path of include files 帮助。

非常感谢，我也试过这个 include_directories($CMAKE_CURRENT_SOURCE_DIR) set(HEADER_FILES $CMAKE_CURRENT_SOURCE_DIR/include/jir_seg/JIRSEGSubClassQGV.hpp)，但它也不起作用，我'不确定，但我认为我做错了，我找不到它！

您是否同时尝试include_directories($CMAKE_CURRENT_SOURCE_DIR) 和include_directories($CMAKE_CURRENT_SOURCE_DIR/include) 和include_directories($CMAKE_CURRENT_SOURCE_DIR/include/jir_seg) - 所有三个指令？

并尝试在PROJECT_SOURCE_DIR 上替换CMAKE_CURRENT_SOURCE_DIR。通常我只使用PROJECT_SOURCE_DIR。

非常感谢，花了我大约5个小时的时间，第一个分层指令解决了我的问题，请把它写成答案:)

【参考方案1】：

CMake 不知道目录的用途，因此如果将头文件放在子目录include 中，则必须使用iclude_directories 指令通知CMake：

include_directories($CMAKE_CURRENT_SOURCE_DIR) 包含目录（$CMAKE_CURRENT_SOURCE_DIR/include） include_directories($CMAKE_CURRENT_SOURCE_DIR/include/jir_seg)
