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

[Brian Davis]

Is there a CMake equivalent to a site-config.jam or user-config.jam

http://www.boost.org/build/doc/html/bbv2/recipies/site-config.html

basically a CMake file the user can put in a project directory that CMake
will read first when using cmake-gui that allows user to specify stuff they
don't want to have to keep specifying in cmake-gui each "delete cache"

such as

set( CMAKE_INSTALL_PREFIX ${CURRENT_LIST_DIR}/install CACHE STRING "" FORCE)
set( CMAKE_DEBUG_POSTFIX d CACHE STRING "" FORCE )


There is cmake.exe

-C <initial-cache>

but requires command line

come to think of it would be nice if
set( CMAKE_GENERATOR_PLATFORM "Visual Studio 12 2013 Win64" )

in desired user config file and CMake would just "make it so" on clicking
Generate.

I can do this with my own projects, by implementing it myself, but when
checking out 3rd party projs they can be all over the map on config
allowing a user-config.cmake would provide mechanism to tame the config
problems.

Desired workflow

1) Checkout 3rd party proj

2) put a CMakeUser.txt or whatever file per project

3) Run CMake GUI Generate

4) Click Open Project

5) Change whatever manual bits in in gui

6) Update project suing git witch branches versions

7) Delete Cache

8) Return to 3

9) Doopy doopy doo whatever else
