@rem Searches for MSBuild.exe. This is the only tool we need to initiate
|
|
@rem a build, so we no longer search for the full VC toolset.
|
|
@rem
|
|
@rem This file is supposed to modify the state of the caller (specifically
|
|
@rem the MSBUILD variable), so we do not use setlocal or echo, and avoid
|
|
@rem changing any other persistent state.

@rem No arguments provided means do full search

@if '%1' EQU '' goto :begin_search
|
|
|
|
@rem One argument may be the full path. Use a goto so we don't try to
|
|
@rem parse the next if statement - incorrect quoting in the multi-arg
|
|
@rem case can cause us to break immediately.
|
|
@if '%2' EQU '' goto :one_arg
|
|

@rem Entire command line may represent the full path if quoting failed.
