Problem solved:

I had the myproja CMakeLists.txt in the same directory as the source:
<root>/proja/CMakeLists.txt # sets the build type through an included file

For myprojb however it was like this:
<root>/projb/CMakeLists.txt
<root>/projb/src/CMakeLists.txt => set the build type here

By the time the 2nd CMakeLists.txt was cracked open, the CMake glue code 
had already determined the build type was ""
