[CMake] Configure never ends when changing compiler

[David Demelier]

Hi there,

After doing a CMake generation, if I try to change the C compiler by
doing cmake -DCMAKE_C_COMPILER=/usr/bin/clang it configures again but
never ends, see :

Installation directories:
        PREFIX          /usr/local
        MANDIR          /usr/local/share/man
        DOCDIR          /usr/local/share/doc/irccd
        MODDIR          /usr/local/share/irccd/modules

Compiling irccd with following options:
        Lua support:    enabled
        Unit tests:     disabled
        Default config: /usr/local/etc/irccd.conf

-- Configuring done
You have changed variables that require your cache to be deleted.
Configure will be re-run and you may have to reset some variables.

Is this a known issue?
