+@brief  Helper script to allow CMake to run some command after setting

+        environment variables.

+

+CMake has commands to run an external program. But remember that each CMake

+command must be backed by multiple build-system implementations. Unfortunately

+it seems CMake can't promise that every target build system can set specified

+environment variables before running the external program of interest.

+

+This helper script is a workaround. It simply sets the requested environment

+variables and then executes the program specified on the rest of its command

+line.

+

+Example:

+

+python run_build_test.py -DFOO=bar myprog somearg otherarg

+

+sets environment variable FOO=bar, then runs:

+myprog somearg otherarg
