Error while installing

First of all in the readme it says "A precompiled, statically linked binary of POPF for Linux x86 is available to download.", but I can't find this file in the distribution.
I tried installing POPF myself on Ubuntu 20.04.1 using mkdir build cd build cmake path_to_src_folder make, but I get this error:

/.../popf/src/VALfiles/TimSupport.cpp:1392:36: required from here
/usr/include/c++/9/bits/stl_tree.h:1117:16: error: no type named ‘value_type’ in ‘struct std::iterator_traits > >’
1117 | __enable_if_t::value>

make[2]: *** [src/VALfiles/CMakeFiles/Inst.dir/build.make:154: src/VALfiles/CMakeFiles/Inst.dir/TimSupport.o] Errore 1
make[1]: *** [CMakeFiles/Makefile2:213: src/VALfiles/CMakeFiles/Inst.dir/all] Errore 2

Reproduce the reported mkdir build, cmake, and make sequence on Ubuntu 20.04, then inspect src/VALfiles/TimSupport.cpp around line 1392 and the README statement about the precompiled binary. Done means the documented installation path works or its compiler incompatibility is addressed, and the binary documentation matches what is distributed.
