Found installed compiler 'MinGW64 Compiler (C)'.

... Looking for compiler 'Microsoft Visual C++ 2015 (C)' ...

... Looking for registry setting 'HKLM\SOFTWARE\Microsoft\VisualStudio\SxS\VC7' 14.0 ...No.

Did not find installed compiler 'Intel Parallel Studio XE 2017 with Microsoft Visual Studio 2015 (C)'.
