[CMake] Question about installing static libraries made with VS 2008

[Ryan Pavlik]

No, you need to install them all: a static library only contains 
basically the object files of the specified sources, archived together.  
Auto* and libtool do some (unpleasant) magic to split and re-combine 
these archives, in some cases, and this is a common question on this 
list.  If you want that behavior (and have this ability) add all the 
sources to your final static library.

Alternatively, you might consider using the export targets file as I 
mentioned in a previous email, as it will preserve transitive link 
dependencies: while it won't put the symbols of pear into fruit, it will 
make a consumer EXE of fruit also link pear.

That is what I see for a project that I build on a Linux system using Automake, Autoconf and Libtool. In the end on the Linux system I have only one static library that I need to install.
