CMake error during build if path contains spaces

[NeoXtreem]

System information

• OS version/distro: Windows 10.0.18362
• .NET Version (eg., dotnet --info): 3.0.100

Issue

• What did you do?
  Ran build.cmd in root folder in a VS 2019 developer command prompt.

• What happened?
  Build failed with error:

EXEC : CMake error : The following variables are used in this project, but they are set to NOTFOUND. [C:\Users\micro\OneDrive - X-treem Software\Development\Repos\General\Frameworks\ML.NET\src\Native\build.proj]
-- Configuring incomplete, errors occurred!
See also "C:/Users/micro/OneDrive - X-treem Software/Development/Repos/General/Frameworks/ML.NET/bin/obj/x64.Debug/Native/CMakeFiles/CMakeOutput.log".
Please set them or make sure they are set and tested correctly in the CMake files:
MKL_LIBRARY
linked by target "SymSgdNative" in directory C:/Users/micro/OneDrive - X-treem Software/Development/Repos/General/Frameworks/ML.NET/src/Native/SymSgdNative
linked by target "MklProxyNative" in directory C:/Users/micro/OneDrive - X-treem Software/Development/Repos/General/Frameworks/ML.NET/src/Native/MklProxyNative

If I move the code to a path without spaces such as C:\Users\micro\OneDrive\ML.NET, it builds successfully. This problem was also described by another user on issue #28 and @eerhardt described the solution in his reply.

• What did you expect?
  Build to succeed regardless of spaces in path.

Could you try running build.cmd from the visual studio developer command prompt?
That fixed it for me when I encountered that error recently.

I had to install the 'Desktop development with C++' workload. That resolved the issue I was having. However, I encountered another issue with CMake due to spaces in the path. I've updated this issue accordingly.

Hi @NeoXtreem , I have changed the name of the directory that includes a build of ML.NET, and reproduced your issue. I get the following error (notice the space in machinelearning-release 3):

EXEC : CMake error : The following variables are used in this project, but they are set to NOTFOUND. [C:\Users\mubal\Documents\GitHub\machinelearning-release 3\src\Native\build.proj]

The issue seems to stem from this line as the path for MKL_LIBRARY is getting distorted by not adding quotes around during the usage of this path (related problem and fix). Also I'm confused what's happening here:

machinelearning/src/Native/build.cmd

Line 31 in f94f359

if /i [%1] == [--mkllibpath] ( set MKL_LIB_PATH=%2&&shift&goto Arg_Loop)

The paths of
@antoniovs1029 @harishsk any ideas?
