CMake Error at CMakeLists.txt:1177 (get_filename_component): get_filename_component called with incorrect number of arguments

meant "you have to pass a cmake install path" like...have to... -DCMAKE_INSTALL_PREFIX=/a/b

x86_64-w64-mingw32-g++: error: unrecognized command-line option ‘-rdynamic’

actually meant "you compiled to i686 previously, apparently cmake isn't happy being run with new params" so git reset --hard && git clean -f or

clear your cmake cache too ... rm -rf CMakeFiles or just check entire repo out again... or add -DWIN32=1

-- Checking for pthread_(g/s)etname_np in 'pthread.h': -- Looking for pthread_getname_np -- Looking for pthread_getname_np - found -- Looking for pthread_setname_np -- Looking for pthread_setname_np - found

this is just wrong, pthread.h has none of that, but seems benign? not if you have SSL enabled, see below:

meant "well, it's missing -lstdc++ but the reason is that it's using `pkg-config --libs srt` but it wants `pkg-config --static --libs srt` so passing that to ffmpeg configure fixes it. `--pkg-config-flags="--static"`
