DESCRIPTION OF CHANGES:
Problem:
The use of generator expressions in the defines compacts the logic neatly but removes the ability to evaluate these conditionals at configuration time. As such, assumptions must either be made or defines wholly dropped when adding configure-time commands like C preprocessing, both of which are wrong.
Solution:
Switch the logic to a more verbose if()-style that guarantees defines that can be known at configure time are resolved.
LIST OF MODIFIED FILES:
M CMakeLists.txt
M cmake/c_preproc.cmake
RELEASE NOTE: CMake build no longer uses generator expressions in defines
TYPE: bug fix
KEYWORDS: cmake, compilation
