Fix the case where cmake --build failed with two project cmds in one file.

This adds a test that uses two project commands in the same CMakeLists.txt
file.  It also adds a fix so that cmake --build will work in that case.
The fix sets the name of the last project command in the top level
CMakeLists.txt in the cache variable CMAKE_PROJECT_NAME.  This variable
is used by cmake --build to find the project name.
