Since this is already working, this is fine probably fine. But was the main issue here the <Exec/> task?

Maybe it would work to make a small <UnixExec/> task that subclasses <Exec/> and replaces all the \ with / in Command? Then base.Execute() would succeed?

@jonathanpeppers : the problem isn't "unix", the problem is double quotes. :-)

"General guidelines", at least on Unix, is to quote anything which could possibly have a space…such as path names! The problem is when:

  1. The "path name" is a directory name, and
  2. The directory name ends with \.

The result is that you escape the quote!

$(_Prepare) $(CmakePath) $(CmakeGenerator) -S &quot;$(_SourceDir)&quot;

Here, $(_SourceDir) will be e.g. $(MSBuildThisFileDirectory), which aways ends with \. If we didn't "fix" $(_SourceDir), we'd have:

make -S "C:\some\directory\" …

The attempt to "sanely" quote the directory name results in an invalid command line.

Does this mean that s,\,/,g is "best"? No; we could instead do:

<_SourceDir>$(CmakeSourceDir.TrimEnd('%5c'))</_SourceDir>

But! If a value can be "part of" the Cmake files, e.g. Cmake variables, those values must use /, not \, because Cmake otherwise attempts to treat \ as an escape character. Thus, $(CmakeExtraArgs) must replace \ with /, as it contains Cmake property overrides that contain paths.

In neither case does a <UnixExec/> class help, unless a "command global" s,\,/,g is desired. Note however that we don't "fixup" $(PrepareNativeToolchain) or $(CmakePath).
