一编译环境

win10

python3.9

vs2019

二 qt creator编译脚本成功

一定记得打开

x64 Native Tools Command Prompt for VS <version>

cd D:\\BaiduNetdiskDownload\\liulanqixiazai\\qtcreator_build
cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo -G Ninja -DCMAKE_PREFIX_PATH="C:/Qt/5.15.2/msvc2019_64/lib/cmake/Qt5;C:/libclang-release_140-based-windows-vs2019_64/libclang/lib/cmake/llvm"  D:\\BaiduNetdiskDownload\\liulanqixiazai\\qt-creator
cd D:\\BaiduNetdiskDownload\\liulanqixiazai\\qt-creator
cmake --build .

三? 不带Nanja的qt creator编译脚本，不行

cd D:\\BaiduNetdiskDownload\\liulanqixiazai\\qtcreator_build
cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo  -DCMAKE_PREFIX_PATH="C:/Qt/5.15.2/msvc2019_64/lib/cmake/Qt5;C:/libclang-release_140-based-windows-vs2019_64/libclang/lib/cmake/llvm"  D:\\BaiduNetdiskDownload\\liulanqixiazai\\qt-creator
cd D:\\BaiduNetdiskDownload\\liulanqixiazai\\qt-creator
cmake -B .build

四? 错误示范?

cd D:\\BaiduNetdiskDownload\\liulanqixiazai\\qt-creator

cmake -S . -B .build -DCMAKE_BUILD_TYPE=RelWithDebInfo -DCMAKE_PREFIX_PATH="C:/Qt/5.15.2/msvc2019_64/lib/cmake/Qt5;C:/libclang-release_140-based-windows-vs2019_64/libclang/lib/cmake/llvm"

Could NOT find elfutils问题未能解决：

尝试如下：

qt-creator/Findelfutils.cmake at master · qt-creator/qt-creator (github.com)

pgjgg@DESKTOP-IQKLRIT MINGW64 /d/BaiduNetdiskDownload/liulanqixiazai/elfutils-latest.tar/elfutils-latest/elfutils-0.187

再尝试：

./configure --enable-maintainer-mode && C:\\Qt\\Tools\\MinGW\\bin\\mingw32-make.exe && C:\\Qt\\Tools\\MinGW\\bin\\mingw32-make.exe check

无用，windows搞make，不会了。

生成成功qt creator，不能运行qt creator。
