[CMake] ExternalProject_Add ... output directy (sln file directory)

[Christophe Demez]

Hi,

I'm currently using one CMakeLists.txt file that will execute an 
external CMakeLists.txt (and dependency).

For this I use the ExternalProject_Add command, but I can't find a way 
to specify where the ".sln" file will be generated.

I have also created StackOverflow question here with more information, 
if someone have an idea for a solution ?
