CMake is finding GCC when building in Windows with `-G "Ninja"` in Azure Pipelines

See original GitHub issue

This recipe is building in AppVeyor, but is failing in Azure Pipelines (win64):

%SRC_DIR%>SET "CMAKE_GENERATOR=Visual Studio 14 2015 Win64"  

%SRC_DIR%>CALL "C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\Tools\..\..\VC\vcvarsall.bat" amd64

In addition to sourcing vcvars, the compiler should be explicitly specified for CMake. This is possible with -DCMAKE_CXX_COMPILER=cl.exe and -DCMAKE_C_COMPILER=cl.exe or setting the standard environmental variables CC=cl.exe, CXX=cl.exe.

The issue seems fixed (probably on Azure side), I’ve temporarily changed the recipe with the original problem to use Ninja again, and it is working! Feel free to close it.
