msbuild: Set UseEnv variable to true

[TheComputerGuy96]

For some reason default Windows headers and libraries can't be found in an older project without those variables being set

[ravenexp]

@ravenexp - Do you have any opinions on this?

These variables look like something the MSVC property files for C++ projects would set internally. See for example MSBuild/Microsoft/VC/v170/Microsoft.Cpp.MSVC.Toolset.Win32.props.

Rather than overriding these globally, I'd first check if setting UseEnv solves the problem for the project in question:

@TheComputerGuy96

Does

msbuild /p:UseEnv=true

work for your project?

[TheComputerGuy96]

@ravenexp UseEnv=true also works (so I set that by default instead)

It's great that it works, but it should not be set by default because it effectively bypasses all configuration settings from the MSBuild project file.

Can you share your MSBuild project file or maybe just the configuration properties part without the source file names? I'll try to figure out what is missing from the msvc-wine MSBuild environment. I want to try to get to the root cause of this issue.

@ravenexp Here's the .vcxproj file: https://github.com/CookiePLMonster/SilentPatch/blob/dev/DDraw/DDraw.vcxproj

Ah, this must be it:

<PlatformToolset>v141_xp</PlatformToolset>

I've never tried targeting Windows 7, much less XP. I'll try to figure out what env vars are required to support this platform.

[TheComputerGuy96]

I'm currently setting /p:PlatformToolset=v143 option to make that project build (and the SetEnv option of course)

I've opened https://github.com/mstorsjo/msvc-wine/pull/152 to address the root cause of this bug. With it applied, your project should now build with:

msbuild /p:Platform=Win32 /p:PlatformToolset=v143 /p:WindowsTargetPlatformVersion=10.0

UseEnv is not required.

@ravenexp I can confirm that MR solves the issue too (with that extra /p:WindowsTargetPlatformVersion=10.0 option; otherwise I get the same build error)

Then I suggest closing this in favor of #152, which solves the actual problem that prevented the needed WindowsTargetPlatformVersion override from working in msvc-wine.
