问题
I have a cmake build that uses gtest - everything works as expected. When I add cotire in I get the error:
error: use of undeclared identifier 'DBL_MAX'
Anywhere #import <float.h> is used
It seems to me that some setting is being fubar'd by adding cotire, but the environment variables look roughly the same

Am I missing something obvious?
