Many thanks in advance. Hi Pere, You could write a wrapper script that sets your environment variables. Since you don't know the actual values for these variables beforehand, you should let CMake generate this script, using configure_file(). That's the way I do it, and it works great.

Thanks for the suggestion. I am doing something similar but on installation. I generate a setup script that then can be used by clients of the project to get the correct environment. I was thinking to have something internal for running the test cases from within the build tree.

[CMake] Running tests using [C++/Python] modules from the build tree
Hi, I am seeking for advise. I would like to run some CTest tests from the build tree, which require C++ or Python modules created in other project directories (packages).
