Comment (by eschnett):

 What you want to ensure is not possible. One can try to carefully order
 the search paths (i.e. first locations for individual libraries, then
 locations containing multiple libraries, then standard locations), but
 this is also not guaranteed to work in all cases.

 Using absolute paths for include paths requires modifying the source code.
 Alternatively, one could set up symbolic links from a single directory
 that is searched first.

 The problem is made even more difficult since both libraries and include
 files depend on other libraries or include files, and their search paths
 may be even more difficult to set.
