Subject: Fix a iconv detection of cmake.
X-Git-Tag: v3.0.0a~455
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ffb72caebdad37a0e3feefbcdae71bc28990f0e4;p=thirdparty%2Flibarchive.git

Fix a iconv detection of cmake.
- Properly find optional directories such as /usr/local/{include,lib}.
- Use FIND_PATH(ICONV_INCLUDE_DIR iconv.h) instead of
  LA_CHECK_INCLUDE_FILE("iconv.h" HAVE_ICONV_H) because detecting libxml2
  headers uses ICONV_INCLUDE_DIR.
