Modified  CMakeLists.txt, I do not have the following devices, disabled them.  The libad9361 looks like a 2G/3G transceiver base station, nor was the libad9361-dev package available on Void Linux.  Doesn't look like the above build error was the source of the apparent dependency error, regardless, including changes to CMakeLists.txt

Error is within the internal pocsag pager decoder sources, likely not finding a header file.

WORKAROUND:
-option(OPT_BUILD_PAGER_DECODER "Build the pager decoder module (no dependencies required)" ON)
+option(OPT_BUILD_PAGER_DECODER "Build the pager decoder module (no dependencies required)" OFF)

... building/compiling is continuing past the compiling previous error.

already been fixed an hour ago, pull again.

[rogerxxxx]

wow. that was quick.

git pull, confirmed some deletions to the specific pager .h file... removed my modification to the cmakelists.txt omitting the pager module build, make clean && make shows everything builds as expected, without the pager module compile error.

fixed.
