should this be check_symbol_exists instead of check_prototype_exists?

check_prototype_exists(isnan math.h HAVE_ISNAN)

should we use in this line check_symbol_exists instead of check_prototype_exists since we are searching in C headers instead of in c++ headers, just like searching for isfinite in line 207?

Well, to my eye it looks right. One finds prototypes in headers and symbols in libraries. Do you have a patch that works better?

Oh sry I got you wrong in the first place. What I intended to say is, like in

geos/CMakeLists.txt

Line 207 in b602db5

check_symbol_exists(isfinite math.h HAVE_ISFINITE)

isn't it looking for a symbol in a header?

[pramsey]

Yes, that one seems odd.

History seems to have caught up with this issue, I see neither test in the code base anywhere anymore.
