FindJUCE.cmake：无法为导入的目标“juce_core”指定源

Posted 2023-02-23

【中文标题】FindJUCE.cmake：无法为导入的目标“juce_core”指定源

【英文标题】：FindJUCE.cmake: Cannot specify sources for imported target “juce_core”

【发布时间】：2020-10-09 11:52:24

【问题描述】：

我正在尝试编译 hello world 程序。我使用了这个链接提供的 CMakeList：https://github.com/remymuller/juce-cmake

我不知道这些错误是什么意思以及如何解决它们。请帮忙。

CMakeLists.txt

$ cat CMakeLists.txt 
cmake_minimum_required(VERSION 3.0)

project(HelloWorld)

set(CMAKE_MODULE_PATH $CMAKE_MODULE_PATH "/home/sulakshana/Documents/evon/work/juce/helloworld/NewProject/juce-cmake/cmake/")

find_package(JUCE REQUIRED 
    COMPONENTS 
        juce_core
        juce_data_structures
        juce_events
        juce_graphics
        juce_gui_basics
        juce_gui_extra
)

set(SOURCES
    ../../Source/Main.cpp
    ../../Source/MainComponent.h
    ../../Source/MainComponent.cpp
)

add_executable($PROJECT_NAME $SOURCES)
set_target_properties($PROJECT_NAME PROPERTIES MACOSX_BUNDLE true)
target_link_libraries($PROJECT_NAME $JUCE_LIBRARIES)
source_group(Source FILES $SOURCES)

我用过这个.cmake：https://github.com/remymuller/juce-cmake/blob/master/cmake/FindJUCE.cmake

文件夹结构：

这里juce-cmake是上面链接仓库的克隆：

$ ls
Builds  juce-cmake  JuceLibraryCode  NewProject.jucer  Source

CMakeLists.txt 的位置：

/Builds/LinuxMakefile$ ls
build  buildCMake  CMakeLists.txt  Makefile

错误：

【参考方案1】：

此模块依赖于 CMake 3.11 中添加的功能。确保您至少拥有该版本。

最后一组错误是因为你只复制了FindJUCE.cmake文件，而没有复制它附带的FindJuceTemplates目录。我建议将整个存储库克隆/下载到您的工作目录（或将其添加为 Git 子模块），然后将其包含在内。您可能需要将CMAKE_MODULE_PATH 指向子目录。

【讨论】：

谢谢。 FindJuceTemplates 目录在我的计算机上的位置应该在哪里？靠近 .cmake 文件？

您应该按原样克隆 github.com/remymuller/juce-cmake 存储库，或者将其下载为 zip 并解压缩。在这两种情况下，结果都应该是项目中的一个新目录。

我已经编辑了这个问题。请看一下。它仍然无法正常工作。请提供一些启示。

我想你的意思是上传你的项目目录的截图？它不见了。此外，在对 CMake 进行如此彻底的更改时，最好丢弃构建目录中的文件并重新运行 cmake ..
