:: Multi-Platform Build Tool for MSVC
::

REM
REM This batch script is used to build the SQLite DLL for multiple platforms
REM and configurations using MSVC.  The built SQLite DLLs, their associated
REM import libraries, and optionally their symbols files, are placed within
REM the directory specified on the command line, in sub-directories named for
REM their respective platforms and configurations.  This batch script must be
REM run from inside a Visual Studio Command Prompt for the desired version of
REM Visual Studio ^(the initial platform configured for the command prompt does
REM not really matter^).  Exactly one command line argument is required, the
REM name of an existing directory to be used as the final destination directory
REM for the generated output files, which will be placed in sub-directories
REM created therein.  Ideally, the directory specified should be empty.
REM
REM Example:
REM
REM                        CD /D C:\dev\sqlite\core
REM                        tool\build-all-msvc.bat C:\Temp
REM
REM In the example above, "C:\dev\sqlite\core" represents the root of the
REM source tree for SQLite and "C:\Temp" represents the final destination
REM directory for the generated output files.
REM
REM There are several environment variables that may be set to modify the
REM behavior of this batch script and its associated Makefile.  The list of
REM platforms to build may be overriden by using the PLATFORMS environment
REM variable, which should contain a list of platforms ^(e.g. x86 x86_amd64
REM x86_arm^).  All platforms must be supported by the version of Visual Studio
REM being used.  The list of configurations to build may be overridden by
REM setting the CONFIGURATIONS environment variable, which should contain a
REM list of configurations to build ^(e.g. Debug Retail^).  Neither of these
REM variable values may contain any double quotes, surrounding or embedded.
REM Finally, the NCRTLIBPATH and NSDKLIBPATH environment variables may be set
REM to specify the location of the CRT and SDK, respectively, needed to compile
REM executables native to the architecture of the build machine during any
REM cross-compilation that may be necessary, depending on the platforms to be
REM built.  These values in these two variables should be surrounded by double
REM quotes if they contain spaces.
REM
REM Please note that the SQLite build process performed by the Makefile
REM associated with this batch script requires both Gawk ^(gawk.exe^) and Tcl
REM 8.5 ^(tclsh85.exe^) to be present in a directory contained in the PATH
REM environment variable unless a pre-existing amalgamation file is used.
