Subject: Do not use -fPIC when linking executables
 cmake includes ${CMAKE_SHARED_LIBRARY_C_FLAGS} in the command line to
 link an executable, and by default this is -fPIC.  Either the use or
 the definition of this variable is wrong, because executables should
 not be linked with this option by default.
 .
 It's not entirely obvious how this variable gets into the command
 line, but you can verify that it does by changing its value to e.g. -D
 SHARED and running make VERBOSE=1.
 .
 Any special options needed for linking with shared libraries can be put
 in CMAKE_SHARED_LIBRARY_LINK_C_FLAGS.
