++# file that is there only because of the poor interaction of the 
++# $<BUILD_INTERFACE:...> with the install(TARGETS...) command. The generator
++# creates an empty string instead of no string and the install(TARGETS...) 
++# takes that empty string as a indication that the code should put the source
++# path in as a source file list (why?).
++#
++# The code here gets inserted into near the end of the cmake_install.cmake
++# file. It reads the flux-targets.cmake file into memory, clears the file,
++# then recreates the file skipping the line that contains the malformed
++# INTERFACE_SOURCES property value.
