我目前正在尝试让CMake在我的Windows7(64位)系统上运行。我想编译TagLib,以便稍后与我正在开发的Qt应用程序一起使用。我想用MinGW (而不是this other question中的Visual C++ )编译它。
我下载安装程序( CMake -2.8.3-win32-x86.exe)并安装它(我还选择将CMake添加到我的路径中)。然后,我转到CMakeLists.txt文件所在的目录并运行cmake .
。然后它给了我一个巨大的错误。

考虑到它标榜自己是一个跨平台的产品,我有点惊讶它开箱即用就失败了。
我尝试将INCLUDE、LIB和LIBPATH (Windows环境变量)全部设置为我的MinGW二进制文件目录(C:\MinGW),但仍然显示相同的错误。我还尝试将CMAKE_C_COMPILER和CMAKE_CXX_COMPILER设置为g++ (C:\MinGW\bin\g++)的位置。
有人知道这是怎么回事吗?
解决方案:
根据tibur的建议,我运行了cmake GUI来创建make文件。然后,我进入taglib目录并运行mingw32-make.exe
来进行实际的构建。

Windows的默认生成器似乎设置为NMAKE。尝试使用:
cmake -G "MinGW Makefiles"
或者使用图形用户界面,并在提示输入生成器时选择MinGW Makefiles。不要忘记清理您试图运行CMake的目录,或者在图形用户界面中删除缓存。否则,它将使用NMAKE重试。

在您的Visual Studio安装目录中有一个vcvars32.bat。您可以在该批处理程序的末尾添加call cmd.exe并启动它。在该shell中,您可以使用CMake或cmake-gui,CMake将知道cl.exe。

对我有效的命令是:
$ cmake -G "MSYS Makefiles" ..
我正在使用MSYS2/Win10编译一个64位的QT5应用程序(使用MINGW64外壳)
