People do weird things.
But, I bet that a lot of people have system that have libintl.h
installed, but they don't install gettext tools. ;-)
Anyway, can I override NO_GETTEXT from command line?
Let's say, I want to bootstrap a new distro?
In the boostrap step, I don't want to build any i18n things,
because the bootstrap package will be thrown away and rebuild again.
I don't want to waste time on building such translation things.

Thanks, my platform relies on this definition!

Sorry, Please ask someone else, check Makefile to see who fixed build
for Solaris and HP-UX.

If Solaris or HP-UX is out of equation,
I'll just write: SH_EXE=/bin/sh ;-)

Linux will install configuration to /etc, Windows (by using msys),
will also do that.
*BSD port installs git with /usr/local prefix, and install
configuration to /usr/local/etc

Does CMake have a macro for check function in which include files?

Now, I looked at this again.
I didn't see the creatation of CreateLinks.cmake anywhere!
