+@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
