Does not build on Windows and Ubuntu

[fatichar]

Visual Studio 2013
error: can not find unistd.h
I commented out the include statement. Then it could not find identifier named daemon. I removed that code too. Then it did not find libzmq. Then it says:

Error 1 error LNK2005: ___xi_a already defined in MSVCRT.lib(cinitexe.obj) D:\Projects\majordomo-master\builds\msvc\libmdp\LIBCMTD.lib(crt0init.obj) libmdp

Ubuntu
autogen was successful.

configure: error: Cannot find required package for libzmq. Note, pkg-config is required due to specified version >= 2.2.0
