I'm having some trouble getting FindGnutls.cmake working correctly. As it
currently stands, I run cmake twice and it works correctly, but it never picks
up the gnutls.h on the first scan. Here's the code in question (the entire
FindGnutls.cmake is at the end of this email):
FIND_PATH(GNUTLS_INCLUDE_DIR gnutls/gnutls.h
HINTS
${PC_GNUTLS_INCLUDEDIR}
${PC_GNUTLS_INCLUDE_DIRS}
"C:/Program Files/*/include" )
For some reason it never finds gnutls.h. I get an error saying it can't be
found. I added the C:/ line because I didn't know how else to make it find the
file. How should I be doing this? What's considered the proper way to find
this without hard-coding a path? Gnutls is kind of annoying in that it has the
version number in it's install directory (i.e. c:\Program Files\Gnutls-2.8.2
and c:\Program Files\Gnutls-2.9.5). This makes it harder to hard-code the
path. The correct path that this should return is "c:\Program
Files\GnuTLS-2.8.2\gnutls\"
