[CMake] CMake equivalent to Boost.Build site-config.jam or user-config.jam

[Brian Davis]

Yes PreLoad.cmake was/is exactly what I am looking for.

I tested it and it works minus the bit about it not workging with:

set( CMAKE_GENERATOR_PLATFORM "Visual Studio 12 2013 Win64" )

but hey it's 99.99 percent of what I need.

Now only if I could find that say in the documentation!

Thanks for the heads up on the feature. Nice!
