[CMake] What is the proper way to 'distribute' .cmake-files?

[Jean-Christophe Fillion-Robin]

Hi Jakob,

In your project, you could add the following:

SET(CMAKE_MODULE_PATH ENV{EXTRA_CMAKE_MODULE_PATH} ${CMAKE_MODULE_PATH})

Then, you could set the environment variable EXTRA_CMAKE_MODULE_PATH to the
central location where you could copy all your common cmake modules,
function or macro ...

See
http://www.cmake.org/cmake/help/cmake-2-8-docs.html#variable:CMAKE_MODULE_PATH
and http://www.cmake.org/cmake/help/cmake-2-8-docs.html#command:set
