Question

仅需遵循GitAhead，即可在“用于VS2017的x64本机工具命令提示符”中构建README。我要做的就是：

在PATH中具有CMake和ninja.exe
检出项目和子模块
在VS Command提示符下，切换到gitahead\build\release目录并运行两次cmake -G Ninja -DCMAKE_BUILD_TYPE=Release -DCMAKE_PREFIX_PATH=C:\dev-tools\Qt\5.12.0\msvc2017_64 ../..

它构建完成并得到一个GitAhead.exe。

现在我想知道是否可以在Qt Creator中打开该项目。根据{{3}}，我只需要在Qt Creator中打开CMakeLists.txt。

起初那根本不起作用。通过反复试验，我提出了以下环境变量，这些变量必须在“选项”>“工具包”>“环境”中设置：

CC=cl
CXX=cl
LIB=C:\Program Files (x86)\Windows Kits\10\Lib\10.0.17763.0\um\x64;C:\dev-tools\VisualStudioBuildTools\VC\Tools\MSVC\14.16.27023\lib\x64;C:\Program Files (x86)\Windows Kits\10\Lib\10.0.17763.0\ucrt\x64
PATH=${PATH};C:\Program Files (x86)\Windows Kits\10\bin\10.0.17763.0\x64;C:\dev-tools\VisualStudioBuildTools\VC\Tools\MSVC\14.16.27023\bin\Hostx64\x64

（这可能不是正确的方法，我不知道自己在做什么。）

但是现在我被卡住了。现在，当我单击“配置项目”时，我得到：

我尝试添加

OPENSSL_ROOT_DIR=C:\dev-projects\gitahead\dep\openssl\openssl

到环境变量，但这没什么区别。我不知道为什么CMake可以在命令行（在VS Command Prompt中）而不是Qt Creator中找到OpenSSL。我该如何调试呢？

在Qt Creator中打开GitAhead时出现“找不到OpenSSL”
