Error: C compiler identification is unknown with Cmake 3.15.1 and Visual Studio 2019

Question

I am trying to build project in Visual Studio 2019 environment with Cmake. But I am getting following Error,

C:\Program Files (x86)\Jenkins\workspace\xyz\build>call "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\Tools\..\..\VC\Auxiliary\Build\vcvarsall.bat" x86_amd64 
**********************************************************************

[vcvarsall.bat] Environment initialized for: 'x86_x64'
-- The C compiler identification is unknown
-- The CXX compiler identification is unknown
CMake Error at CMakeLists.txt:2 (project):
  No CMAKE_C_COMPILER could be found.

I have included following lines in my execution to run the build,

call "%VS160COMNTOOLS%\..\..\VC\Auxiliary\Build\vcvarsall.bat" x86_amd64
cmake ../xyz/ -G "Visual Studio 16 2019" -A x64

Following system environment variables are added to help the execution,

VCTargetsPath: C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\MSBuild\Microsoft\VC\v160\

VS160COMNTOOLS: C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\Tools

Can some one explain me what could be a solution to this problem?

Thank you for reply/comment/answer!
