[CMake] Fwd: Visual Studio command line from CMake

[Rob McDonald]

Thanks for the tip, but that hasn't been very helpful to me.  Perhaps I'm
not doing it right.  Here is a bit of CMake code so the conversation can be
more concrete.  Perhaps someone on list can try it out...

You'll need these two files...

http://www.fltk.org/software.php?VERSION=1.3.2&FILE=fltk/1.3.2/fltk-1.3.2-source.tar.gz
http://seriss.com/people/erco/fltk/tmp/vsnet-makefiles.0.85.zip

Place them in the same directory with the following in the CMakeLists.txt

CMAKE_MINIMUM_REQUIRED( VERSION 2.8 )

INCLUDE( ExternalProject )

SET( VS_MAKEFILE_ZIP vsnet-makefiles.0.85.zip )

ExternalProject_Add( FLTK
URL ${CMAKE_SOURCE_DIR}/fltk-1.3.2-source.tar
UPDATE_COMMAND
 ${CMAKE_COMMAND} -E copy_if_different
${CMAKE_SOURCE_DIR}/${VS_MAKEFILE_ZIP}
<SOURCE_DIR>/${VS_MAKEFILE_ZIP}
 COMMAND
${CMAKE_COMMAND} -E tar -xzf <SOURCE_DIR>/${VS_MAKEFILE_ZIP}

 PATCH_COMMAND ""
CONFIGURE_COMMAND ""
BUILD_COMMAND ""
 INSTALL_COMMAND ""
)


To build this manually, first, unzip both files into the same directory.
 Then, launch the Visual Studio Command Prompt, usually accessed via
the VS/vcvarsall.bat
program included with Visual Studio.

Once both files are unzipped into the same directory, and you are in the VS
prompt environment, you can build FLTK using the batch program 'gmake.bat'.

For better or worse, it prompts the user to input for Debug or Release, and
then for Verbose or Quiet.  If you make a simple text file with the entries
one per line...

******* input.txt
R
Q
*******

You can feed that to the batch program thusly....

gmake < input.txt

Alternately, if you can set DEBUG=R and VERBOSE=Q environment variables to
the shell used to run 'gmake.bat', then you don't have to feed the text
file for the user-input prompts.

I tried something like the following....

BUILD_COMMAND
   ${CMAKE_COMMAND} --build <SOURCE_DIR> -- gmake

But, it didn't seem to do anything useful....
