One of our internal projects incorporates a static build of OpenImageIO,
which itself uses a static build of Boost (1.59.0)
In the process of updating 1.5.21 to 1.8.14 I get the build failure below.
The issue appeared to be incorrect ordering of the Boost libraries;
boost_thread depends on boost_system, and so the order must respect this
for static links.
I was able to adjust it with the following patch which I am submitting for
inclusion; though perhaps someone who knows anything about cmake will want
to review this with suspicion :)
I also noted that this line pre-dates even our previously-working
OpenImageIO. I assume some additional Boost symbols are now used.
Unfortunately I have not had time to investigate, but happy to receive any
further guidance.
Thanks

We are building static OpenImageIO where constituent libaries are also
static, with the build failure seen below.
At link time, the following command is executed via cmake:
... libOpenImageIO_Util.a -Wl,-Bstatic -lboost_filesystem -lboost_system
-lboost_thread ...
But the ordering is not correct, as boost_thread depends on
boost_system, it must precede it in the list of libraries for static
builds.
Transcript of the build failure, with Boost 1.59.0:
