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.
