Question

我正在尝试使用CMake构建基于QT的应用程序，一切顺利。我遵循了this教程，我可以构建我的应用程序。现在我想在使用npm run build构建之前运行add_custom_command它似乎没有按预期进行。

构建过程失败，

RCC: Error in 'tray-icon/systray.qrc': Cannot find file 'html/js/app.full.js'
AUTORCC: error: process for.build/Debug/x64/tray-icon/CMakeFiles/tray-icon.dir/qrc_systray.cpp failed:
RCC: Error in 'tray-icon/systray.qrc': Cannot find file 'html/js/app.full.js'

您能否告诉我如何在npm的构建验证步骤之前执行tray-icon/systray.qrc命令？

这是我的cmake文件

cmake_minimum_required(VERSION 2.8.11)
project(tray-icon)

set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)
set(CMAKE_INCLUDE_CURRENT_DIR ON)

find_package(Qt5Widgets 5.5)
find_package(Qt5Qml 5.5)
find_package(Qt5WebEngine 5.5)
find_package(Qt5WebEngineCore 5.5)
find_package(Qt5WebEngineWidgets 5.5)

# generate rules for building source files from the resources
set(SOURCES tray-icon.cpp window.cpp systray.qrc)

set(CMAKE_VERBOSE_MAKEFILE 1)
#adds target
add_executable(tray-icon ${SOURCES})

# custom build command for javascript part of the application
add_custom_command (
  TARGET "tray-icon"
  PRE_BUILD COMMAND npm run build
)

# Find the QtWidgets library
target_link_libraries(tray-icon
        Qt5::Widgets
        Qt5::WebEngine
        Qt5::WebEngineWidgets)

install(TARGETS tray-icon DESTINATION .)

PS：我的最终解决方案如下

# custom build command for javascript part of the application
add_custom_target(
  tray-icon_automoc
)
add_custom_target (
      npm-target
      COMMAND cd ${PROJECT_SOURCE_DIR} && cd html && npm install && npm run build
)

Answer 1

您可以尝试add_custom_target和add_dependencies。

add_custom_target (
    npm-target
    COMMAND npm run build
)
add_dependencies(tray-icon npm-target)

要克服评论中提到的问题，您应该能够使用AUTOGEN_TARGET_DEPENDS目标属性添加依赖项。可以将其设置为_automoc目标的依赖项列表。

在特定的cmake目标之前运行npm命令
