[CMake] a question on ExternalProject_Add

[Yifei Li]

Hi folks,

I'm using VS2012+cmake2.8.12. My problem is that CMake failed to generate
the correct path to my external project. For example:

Project("{...}") = "external", "external.vcxproj", "..."

whereas 'external.vcxproj' should be something like
..\path\to\external.vcxproj

Here is how I use ExternalProject_Add command:

ExternalProject_Add(external SOURCE_DIR
${CMAKE_SOURCE_DIR}/../../int/external CMAKE_ARGS ..
BINARY_DIR ${CMAKE_SOURCE_DIR}/../../int/external/build)


Any help is highly appreciated!
