git clone; ./build.cmd fails

[guylangston]

@benaadams suggest that I raise this issue as he had numerous reports from the wild:

• https://twitter.com/ben_a_adams/status/1229750159095009280
• https://twitter.com/ben_a_adams/status/1228334444525891584

Steps to reproduce:

• git clone https://github.com/dotnet/runtime.git
• ./build.sh

Results in error:

Build FAILED.

I ran in to this when my installed cmake version was below 3.15.5. Are you using a version of cmake that is older than that?

@jkoritzinsky

cmake version 3.15.19101501-MSVC_2

@guylangston
@jkoritzinsky can probably confirm but the last I understood, the version of cmake that ships with Visual Studio is a little out of date. Can you try downloading the latest version, ensure it is on your PATH (make sure cmake --version output is the one you just installed), and seeing if that resolves the issue?

$ choco install cmake --installargs 'ADD_CMAKE_TO_PATH=System'

@vcsjones Looks like you were correct.

https://github.com/dotnet/runtime/blob/master/docs/workflow/requirements/windows-requirements.md#cmake specifies 3.15.5 -- one would think that "3.15.19101501-MSVC_2" would meet that criterion but I'm guessing that 19101501 is not actually the 19 millionth revision of 3.15 and is just some unusual versioning scheme.

Closing since this seems resolved.
