[Cmake] Multiplatform build in a shared source code tree ???

[Andy Cedilnik]

Hi Holger,

You can do out of source build. The way you do this is to specify
different source and build directory. For example on linux:

mkdir Project-Linux
cd Project-Linux
ccmake ../Project

On Sun:

mkdir Project-Sun
cd Project-Sun
ccmake ../Project

On Windows:

mkdir Project-Windows
cd Project-Windows
cmake ../Project -G"Visual Studio 6"

Or open CMakeSetup and specify source to be Project and build be
Project-Windows.
