v0.40.0

What's Changed

• fix: do not activate the MSVC Windows toolchain by default by @aminya in #286
  This improves the reliability of project_options when MSVC is used for cross-compilation. Previously the msvc_toolchain() function was called automatically, but now you should do it manually in case you don't hit the corner cases.

• fix: correct message level for cppcheck fallback standard by @FeignClaims in #285
