# Environment variables
# Note: On trusty we need to build Armadillo and boost ourselves (the system versions are too old)
# Note: On OSX we can't test SYSTEM_Boost=OFF due to excessive log size (https://github.com/CCPPETMR/SIRF-SuperBuild/issues/167)
# Note: currently ACE is not building correctly, so ACE is not built on any configuration https://github.com/CCPPETMR/SIRF-SuperBuild/issues/#174
# Note: on Trusty, g++-7 causes errors with the system ACE, so cannot use g++-7 or later https://github.com/CCPPETMR/SIRF-SuperBuild/issues/169
# Note: altering the matrix here will cause re-building of caches,
# so try to keep this concise to avoid need to update
# Note: the line above each `env` contains a resume of the parameters passed to cmake.
#       + or - refer to the value of the parameter affecting the specific package is passed to cmake:
#       i.e. -boost == -DUSE_SYSTEM_Boost=OFF, which means that Boost will be built.
