Build of poppler on 10.8 fails in a pretty absurd way:
{{{
-- Configuring done
CMake Error in qt5/src/CMakeLists.txt:
No known features for CXX compiler

"Clang"

version 5.0.2.
}}}
https://build.macports.org/builders/ports-10.8_x86_64_legacy-
builder/builds/71069

Weird enough it works on 10.7.

Comment (by ryandesign):

It's easy enough to reproduce this on a newer system such as High Sierra
with:
{{{
sudo port configure poppler-qt5 configure.compiler=macports-clang-6.0
}}}

Looks like a known issue. See:

<https://stackoverflow.com/questions/38027292/configure-a-qt5-5-7
-application-for-android-with-cmake/40256862#40256862>

and

<https://bugreports.qt.io/browse/QTBUG-54666>

and in particular

<https://bugreports.qt.io/browse/QTBUG-57886>

I tried the suggested workaround, it it got past the initial issue, but
then it died later with unrecognized compiler characteristics.

This issue seems to be happening in a number of different tickets, and we
should probably condense it into one to follow it along.

This should be fixed with a simple patch for poppler:

Ah, just came down to improperly-written CMakeLists.txt files in the end.
Seems a common enough problem out there that I'm surprised to see it still
on the qt bug tracker. The cmake docs are clear enough that the
requirements have to come first...good job nailing it.
