【Qt】【CMake】-CMakelists.txt-编译错误：No SOURCES given to target: project

1.【编译错误】：

项目中，找不到源文件！

CMake Error at CMakeLists.txt:36 (add_library):

  No SOURCES given to target: project

CMake Generate step failed.  Build files cannot be regenerated correctly.

make: *** [cmake_check_build_system] Error 1

16:10:33: The process "/Users/goodmao/Qt_all_version/Qt5.15.4/Tools/CMake/CMake.app/Contents/bin/cmake" exited with code 2.

Error while building/deploying project base (kit: Desktop (arm-darwin-generic-mach_o-64bit))

When executing step "CMake Build"

16:10:33: Elapsed time: 00:00.

2.【错误原因】：

项目配置不正确。

一般是代码文件路径配置问题。

3.【解决方法】：

修改路径正确即可。

4.【例子】：

项目路径如下：

project

|-CMakeLists.txt

|-src\

|-header\

此时，CMakeLists.txt中的宏  ${ CMAKE_CURRENT_SOURCE_DIR }，

表示：project/

那么，src源文件的路径，配置如下：

aux_source_directory(${CMAKE_CURRENT_SOURCE_DIR}/src/.   PROJECT_SRC)
