 I've attached the output of the last command, as it is quite long. The
 output directs me to a QGIS log, which in turn directs me to a CMAKE log,
 so I have attached both of those as well.

 I am not familiar with the logs, but a few items jump out at me.

 The first two are failing substitutions, first in qwt (seen in terminal
 output), and then in qgis (seen in the qgis log).

 The second is a warning during configuration, found in the qgis log.

 {{{
 :info:configure CMake Warning at CMakeLists.txt:320 (FIND_PACKAGE):
 :info:configure   By not providing "FindQJSON.cmake" in CMAKE_MODULE_PATH
 this project has
 :info:configure   asked CMake to find a package configuration file
 provided by "QJSON", but
 :info:configure   CMake did not find one.

 it has been
 :info:configure   installed.
 }}}

 I've tried setting both CMAKE_PREFIX_PATH and QJSON_DIR, but as I don't
 know what it's expecting, my efforts haven't yielded any changes yet.
