So, I had this discussion on the kde list.  pkg-config is great if it is 
installed on the machine you are using.  However, since it is not a 
default install on anything other than linux machines, you really don't 
want to depend on it.  Sun, SGI, OSX, and Windows may or may not have 
pkg-config installed. However, they may have the software you are 
looking for.  If you don't find it (the software you are looking for) 
because there is no pkg-config, then people will not like your software. 
  I suppose if you really wanted to depend on pkg-config, you would look 
for it in the first line of your project and error out with a 
FATAL_ERROR if it is not found.  Tell the user to install pkg-config 
before configuring your project.  For example, I don't think pkg-config 
is on any machines at Kitware other than linux machines.
