[CMake] CMAKE 2.8.5 - CMAKE_GENERATOR Bug?

[Sarnath K - ERS, HCLTech]

Hello John,

I can +vely see this behavior with the latest 2.8.7 version as well.
I am using a windows 64-bit machine with Visual studio 2008 installed on it.

This is how I use Externa Project Add command:
"
    include(ExternalProject)
    ExternalProject_Add(
        gen
        CMAKE_GENERATOR "Visual Studio 9 2008"
        URL file://${CMAKE_SOURCE_DIR}/src/tools/gen
        INSTALL_COMMAND ""
    )
"

The CMakeLists.txt hosting this ExternalProject_Add is generated using "NMake Makefiles" - which uses the default 64-bit build configuration.
A verbose Makefile generation nails the issue.
The "gen" project is generated as <cmake "-G Visual Studio 9 2008"> which screws things up.

Can somebody please help me with this?

Thanks,
Best Regards,
Sarnath

I am not seeing this breakage. However you are 2 versions behind in cmake.
