CMake command not working on Windows 10

[kandroid29]

I wanted to build the project on my Windows10 PC. When I executed the following command
cmake -H. -DCMAKE_TOOLCHAIN_FILE=vcpkg\scripts\buildsystems\vcpkg.cmake -Bbuild -G "Visual Studio 15 2017"
it complaint "Argument "." to --help-command is not a CMake command. Use --help-command-list to see all commands."

I guess it was related to the -H. argment passed to cmake, but I had not figured out what was the problem.

Please help me fix this issue

Your System:

• OS: Windows 10 64bit
• CMake version: 3.19.0

Could you try and out-of-source build without the -H. and -B flags?

1. Create an empty directory and cd into it
2. From above directory, call something like:

   cmake -DCMAKE_TOOLCHAIN_FILE=vc…\vcpkg.cmake -G "Visual Studio 15 2017" D:\OpenSource\warzone2100
   

I'm assuming here that OpenSource\warzone2100 contains the source files (and CMakeLists.txt).

See if that works for you.

What I tried was replacing the -H. with . and it works fine, following is the command I used:
cmake . -DCMAKE_TOOLCHAIN_FILE=vcpkg\scripts\buildsystems\vcpkg.cmake -Bbuild -G "Visual Studio 15 2017"

I guess -H has different effect on different platform or with different CMake version

I think what you advised will also work
Thanks:)

Ok, great! If you found the -H. line in Warzone2100 documentation, then it would be good to point out where so it can be fixed.

Please close this issue, if it has been resolved. Thanks!

It's under the Howt to Build -> Windows using MSVC section in readme.md file;
Hopefully you can fix this so other developer would not be stuck with the cmake command error.
Thanks!
