为什么我不能让 cmake 在没有 VS 生成器的情况下在 vs 代码中使用 vcpkg

Question

My DCMAKE_TOOLCHAIN_FILE option is set appropiately. Intellisense recognises the library that i am using and yet i can't seem to get it working. Usually i get. If i don't set the target architecture it goes on to build without vcpkg. If i do try to set it it says that it is not supported by the genrator which is actually to be expected since in the cmake --help ony The VS generators have the [Arch] tag

CmakeLists.txt

PS D:\.WorkSpaces\KeyHUD> cmake -G "MinGW Makefile" -A=Win32 "-DCMAKE_TOOLCHAIN_FILE=D:\.Installs\vcpkg\scripts\buildsystems\vcpkg.cmake" 
CMake Error: Could not create named generator MinGW Makefile

Answer 1

You need to define VCPKG_TARGET_TRIPLET in your cmake call (probably x64-mingw) to avoid the warning and drop the -A=Win32

also cmake -G "MinGW Makefile" has a typo it should be cmake -G "MinGW Makefiles" (missing the s)

so try:

cmake -G "MinGW Makefiles" -DCMAKE_TOOLCHAIN_FILE=D:\.Installs\vcpkg\scripts\buildsystems\vcpkg.cmake -DVCPKG_TARGET_TRIPLET=x64-mingw
