Broken export of boost linking flags

[tskisner]

Hello @arahlin , just a heads up that the recent change to Spt3gBoostPython.cmake:

spt3g_software/cmake/Spt3gBoostPython.cmake

Line 54 in a64249c

set(CMAKE_FIND_PACKAGE_PREFER_CONFIG TRUE)

has broken the ability for the so3g package to get boost linking information by using the build/cmake-install/Spt3gConfig.cmake file. Can you give more information about what problem that was trying to fix? I have not yet dug into this any deeper to see why the various Boost::filesystem, Boost::python, etc are no longer available, but thought I would try to get more information about this change first.

Interesting, how do you install boost, what version are you using, and what are the errors you get? Newer boost versions ship with their own cmake config files that are supposed to provide the same variables and targets, and newer versions of cmake issue lots of warnings about potential mismatches if the cmake find module is used instead of the boost config. This flag just suppresses that warning and tries to use the config if it can find it.

Fixed with #71
