# The following is a workaround that lets 'fpcalc' (the final executable generate) to compile.
#
# In theory this shouldn't be needed, but it would appear the 'cmake' rule to Chromaprint
#   don't correctly work out that linking in a static -lavcodec means that -lz also need to be present.  
# Awkward to try and change the rule within cmake, so the decision was made to include it through
#   the LDFLAGS environment variable, even though that means it's presented to all the linking
#   commands in the project.

# How did we get here?
#
# The fix is considered a small price to pay in working through a more complicated sequence of
# errors we had been getting.
#
# 1. With default params, chromaprint generates both static and shared libraries.  However, compilation
#     failed trying to generate the shared library, as it could not link against the static
#     libavcodec.a (-fPIC issue).
# 2. So, next we went back to 'ffmpeg' and changed its configure statement to enable shared libraries.
#     However, this lead to a new linking error to do with 'inflate' (in libz) not being found.
#     (It wasn't clear at that point which libz it should be looking for.  It was thought that it
#     was probably a system-wide installed one, and perhaps one that was perhaps just the .so file)
# 3. The decision at that point was made to bundle a version of libz within the 'devel' folder
#     to this extension, and point packages known to need it explicity at that.
#
# Step 3 resulted in successful compilation, notwithstanding, the little bugbear that 'fpcalc'
#   fails to include -lz in its linking command (hence the workaround used here!)
