c++ headers are not found by fortify's msbuild


there is a simple project that i want to scan with fortify sca 19.

when i use VS2017's msbuild, it builds the project but when i use fortify provided msbuild, it says: "Cannot open include file: 'stdio.h'".

i tried to add whatever environment variables i could but still getting this error.

i don't know if it helps but i scan .net code just fine, seems c++ configurations are messed up.
