[IGSTK-Users] Two Questions:

[Patrick Cheng]

Hi Tim,

The way IGSTKSandbox works is:

1. When you cmake IGSTKSandbox, you have to give the binary directory of 
main IGSTK library. You don't necessarily need to build the main IGSTK 
library, but you have to at least run the CMake configure on IGSTK, so 
it will generate the "IGSTKConfig.cmake" in the binary directory.

2. CMake will then, parse the "IGSTKConfig.cmake", and find the source 
directory of IGSTK, and copy all the latest source code from IGSTK to 
"IGSTKSandbox-Binary/SourceLatest"

3. When build IGSTKSandbox, it will build the stand alone 
IGSTKSandbox.lib from scratch, it's not linking to the IGSTK.lib.

I hope this clarifies the build process.
