[CMake] Using the -C option to cmake

[Christian Arnault]

Hi,

I wanted to factor out some initial stuff of my CMakeLists.txt that I 
systematically include.

typically I include the following lines at the beginning of all my 
CMakeLists.txt:

cmake_minimum_required(VERSION 2.8)
function (AA)
   message ("calling AA")
endfunction()

AA()

Then I thought by using the -C option as follows:

 > cmake --build=. -C %CMTROOT%\Init.cmake ..\CMakeLists.txt

with Init.cmake file containing

function(AA)
   message("calling aaaa")
endfunction()

This would be equivalent.

Apparently this is not the case. In particular, the function definitions 
are not transmitted by this mechanism

loading initial cache file ...\Init.cmake

... the functions defined in Init.cmake are not recognized

Of course I could 'manually' include my module in all CMakeLists.txt but ...

Can someone explain why?

Or, how could I obtain what I need?



Thanks for any hint

Regards
Christian
