You do not need a Professional or Enterprise license to use the Visual Studio Build Tools:

> Previously, if the application you were developing was not OSS, installing VSBT was permitted only if you had a valid Visual Studio license (e.g., Visual Studio Community or higher).

From (https://devblogs.microsoft.com/cppblog/updates-to-visual-stu...). For OSS, you do not even need a Community License anymore.
