Is the library built by LibRaw.sln thread-safe?

I wanna build LibRaw using LibRaw.sln provided in the downloaded source package, instead of the steps using nmake described here: That webpage claims that "Only the thread-safe library is built under Win32", which implies that the output libraw.dll is thread-safe. So my question is: is the library built by LibRaw.sln still thread-safe?

My environment and settings:
- Windows 10 version 1803, 64bit
- Visual Studio 2015 Update 3
- Release x64 build

Thank you.
