CMake + Intel 19 + VS 2019 -> Error while determining compiler.
Error: error : Element <LanguageStandard> has an invalid value of "Default".
Relevant Intel issue: https://software.intel.com/en-us/forums/intel-c-compiler/topic/811512
Possible Solution:
Add <LanguageStandard>stdcpp14</LanguageStandard>
in <ClCompile>
to VS-10.vcxproj.in
in share/cmake-3.15/Modules/CompilerId
Probably an Intel integration issue and not a CMake issue? Just documenting here if questions arise.
