Review request for Calligra.


Summary
-------

When iconv is installed in a path not searched by default by the compiler (such as /usr/local on FreeBSD), the wv2 checks for iconv fail, as the linker does not find libiconv.so to link to it and the compiler cannot find iconv.h.

This patch passes ICONV_LIBRARIES and ICONV_INCLUDE_DIR to the try_run call, making sure the program compiles and links fine.

Testing
-------

The FreeBSD user who was having wv2 detection problems says it worked fine.


Thanks,

Raphael
