Several changes: COMPILE_DEFINITIONS is now depricated. If you want to specify some, use CMAKE_FLAGS -DCMAKE_DEFINITIONS:STRING=...; same goes for libraries, include path, ... It now detects wether the file is C or C++ and uses the apropriate project command, it also does the right thing when doing try_compile, so it does not execute configure for every single try_compile
