Here are some options:<br><br>1. Manually set your environment variables in Control Panel->System or your ~./.bashrc or shell configuration file of choice.<br>2. If you need multiple different configurations define them in multiple files which you source into your existing shell. In Linux you would do something like ". new_settings.sh". In Windows I'm guessing you just run a ".bat" file with the settings in it.<br>
3. Use bash, tcsh, etc. functions (Linux only I believe)<br>4. Use CMake to create a script that sets environment variables and invokes a new console ("bash") or a graphical window ("konsole)<br>5. Use CMake to create a script that you then manually source in via ". new_settings.sh" or running a batch file<br>
<br>I'm sure there are plenty more. The major problem of course is that CMake is not meant to create persistent environment variables because it's not meant to launch your build tool of choice, be that Visual Studio, "gnome-terminal", Kdevelop, eclipse, etc.<br>

Thanks, but I do not think this is what I want. set($ENV{VAR} "some_data") in a cmake-script will set an enviroment variable AND delete it when the script terminates. Is this not true when using -P? Do I actually need an execute_process-command (or anything else) in my script that will set the environment variable?<br>

Hello and sorry for my late response!<br><br>I can not get this to work. When i execute the command COMMAND ${CMAKE_COMMAND} -E ${template.cmake}<br>
I get an error saying something like:</blockquote></div><div><br>I believe there was a minor typo in the post.
