I do sympathise ... cmake causes me lots of trouble too.

What I generally end up doing is using a tar image i have of the library source 
on which cmake already ran once ... as long as things haven't changed too much 
I can then use this to build the library on new systems (usually with some 
manual editing of one file).
Basically that means I avoid running cmake and hope that the config stored in 
the tar image will work on the system I'm building for.

I can mail you a copy of that tar image if you like ... you could then try:
1. untar it
2. change directory into the Build subdirectory
3. edit the file CMakeCache.txt to change paths to executables like clang, so 
they match your system
4. type 'make'
