Build fails with MSBuild

[philomath213]

I'm trying to build SEAL 3.5.1 with MSBuild on Windows in Powershell.
The build fails when I use the project file native\src\SEAL.vcxproj .

PS C:\Users\philomath213\SEAL> msbuild .\native\src\SEAL.vcxproj /p:configuration=Release /p:platform=x64
...
...
...
"C:\Users\philomath213\SEAL\native\src\SEAL.vcxproj" (default target) (1) ->
(ClCompile target) ->
  C:\Users\philomath213\SEAL\native\src\seal\util\ztools.cpp(16,10): fatal error C1083: Cannot open include file: 'zlib.h': No such file or directory [C:\Use
rs\philomath213\SEAL\native\src\SEAL.vcxproj]

    19 Warning(s)
    1 Error(s)

When I use the solution file SEAL.sln building the project SEAL.vcxproj pass and I can findthe library built in \lib\x64\Release\seal.lib
msbuild SEAL.sln /p:configuration=Release /p:platform=x64
but it continue the build the others projects (examples, test, dotnet, ....).

Anyway to build SEAL.vcxproj project only?

Edit:

You can find the logs here.

Thanks for your report. The reason is that SEAL.vcxproj uses ${SolutionDir} to define additional include directories. When building the project itself, this variable is not set, due to the missing solution. There are two solutions:

1. Build the project with a SolutionDir argument: msbuild .\native\src\SEAL.vcxproj /p:configuration=Release /p:platform=x64 /p:SolutionDir=.\.
2. Or replace all $(SolutionDir) in SEAL.vcxproj with $(ProjectDir)\..\...

Now you can build either a standalone project or the entire solution.

Thank you @WeiDaiWD for your answer.
The 1st solution works fine, while in the 2nd solution, the SolutionDir argument should be /p:SolutionDir=..\..\ since it will be passed as string and the relative path won't be resolved.

You are right. Fix 1 has been implemented internally. It will appear in the next release.
