More testing seems to indicate that check_symbol_exists won't find any
typedef defined in headers.
Looking a the CheckSymbolExists.cmake file, the following .c is
generated as a test:
#include <runetype.h>
void cmakeRequireSymbol(int dummy,...) {
(void)dummy;
}
int main() {
#ifndef wint_t
cmakeRequireSymbol(0, &wint_t);
#endif
return 0;
}
Unfortunately, you can't use #ifndef to test for the existence of a
typedef, hence you get a compile failure and the result of the test is
false.
Is there another check which is typedef/define agnostic? I'm sure I
could write my own, but this seems like it should be included in the
standard cmake library.
