Issue when running build-extern.cmd on win10

[VitaMeanC]

Hi Sebastian,

when I ran build-extern.cmd on my win10 PC, I got this error:

[1/11] Performing build step for 'glviz-debug'
FAILED: glviz-debug-prefix/src/glviz-debug-stamp/glviz-debug-build
cmd.exe /C "cd /D H:\Repos\surface_splatting\.extern\build\glviz-debug-prefix\src\glviz-debug-build && D:\cmake-3.17.0-win64-x64\bin\cmake.exe -P H:/Repos/surface_splatting/.extern/build/glviz-debug-prefix/src/glviz-debug-stamp/glviz-debug-build-.cmake && D:\cmake-3.17.0-win64-x64\bin\cmake.exe -E touch H:/Repos/surface_splatting/.extern/build/glviz-debug-prefix/src/glviz-debug-stamp/glviz-debug-build"

I checked out glviz-debug-build-out.log (btw glviz-debug-build-err.log is empty), and found this:
Error: This file requires compiler and library support for the ISO C++ 2011 standard. This support is currently experimental, and must be enabled with the -std=c++11 or -std=gnu++11 compiler options.

Then I followed a tip from google and added SET(CMAKE_CXX_FLAGS "-std=c++11 -O3") to ~\.extern\build\glviz-prefix\src\glviz\CMakeLists.txt

But the output from cmd stayed the same, and I found this in glviz-debug-build-out.log:

Could you help me out with this problem?

Thanks in advance!

Do you have a GNU C/C++ compiler in your PATH? The CMake Ninja generator defaults to gcc, g++ if its available in the path.

You can attempt to set CMAKE_C_COMPILER, CMAKE_CXX_COMPILER explicitly to cl.exe in the CMake generate run.

I found myself using a wrong version of minGW, and it's OK now.
Thanks a lot for your help : )
